ORIGINAL ARTICLES
Antimicrobial resistance of bacterial isolates from respiratory secretions of ventilated patients in a multi-specialty hospital
Nishat Hussain Ahmed, Tabish Hussain, Indu Biswal
July-September 2015, 5(3):74-78
DOI
:10.4103/2231-0770.160233
PMID
:26229758
Context:
Ventilator-associated pneumonia (VAP) is a common nosocomial infection occurring in intensive care unit (ICU) settings. VAP occurs due to interplay of three factors - impaired host defense, access of large numbers of pathogenic bacteria to the lower respiratory tract and the virulence of the organism. Knowledge of colonizing microbial flora and their antibiogram in ventilated patients is of great importance in timely institution of empirical therapy, so that mortality and morbidity due to VAP can be reduced.
Subjects and Methods:
A prospective study was performed over a period of 6 months in a multi-specialty hospital to determine the various pathogens in respiratory secretions and to determine the prevalence of multidrug resistance (MDR).
Results:
Pseudomonas aeruginosa
(26%
), Acinetobacter
(26%)
, Klebsiella pneumoniae
(26%)
,
followed by
Escherichia coli
(15%),
Staphylococcus aureus
(6%) and
Citrobacter spp.
(1.5%) were the common pathogens isolated in our study. In all, 72.73% (48/66) bacterial isolates were isolated from medical ICU, while 25.76% (17/66) were isolated from surgical ICU. Only one strain (
Acinetobacter)
was isolated from pediatric ICU. Fifty-seven (86.36%) of the 66 pathogens in our study were MDR.
Conclusion:
There is increasing colonization of pathogenic bacteria in ventilated patients admitted in ICUs, which are predominantly MDR. These colonizers may cause infection resulting in VAP. Judicious use of antibiotics, guided by local antibiotic resistance profile coupled with strict infection control practices alongside application of VAP bundle are important measures to prevent these pathogens from causing VAP in ICU patients.

Tenofovir induced lichenoid drug eruption
Mrinal Gupta, Heena Gupta, Anish Gupta
July-September 2015, 5(3):95-97

Cutaneous adverse reactions are a common complication of anti-retroviral therapy. Tenofovir is a newer anti-retroviral drug belonging to the nucleotide reverse transcriptase inhibitor group. Systemic adverse effects like nausea, vomiting, diarrhea, hepatotoxicity and renal toxicity are common with tenofovir but cutaneous adverse effects are rare. Lichenoid drug eruptions are a common adverse effect seen with a large variety of drugs including antimalarials, antihypertensives, nonsteroidal anti-inflammatory drugs and diuretics. Lichenoid drug eruption is a rare cutaneous adverse effect of tenofovir with only a single case reported till date. Here, we report a case of tenofovir induced lichenoid drug eruption in a 54-year-old human immunodeficiency virus affected male who presented with generalized lichenoid eruption after 6 weeks of initiation of tenofovir and complete clearance on cessation of the drug.

Effects of dexmedetomidine and clonidine as propofol adjuvants on intra-operative hemodynamics and recovery profiles in patients undergoing laparoscopic cholecystectomy: A prospective randomized comparative study
Naz Anjum, Hussain Tabish, Saha Debdas, Hembrom P Bani, Choudhuri Rajat, Ghosh Dastidar Anjana Basu
July-September 2015, 5(3):67-73
DOI

PMID
:26229757
Context:
Alpha-2 (α2) adrenergic receptor agonists, clonidine and dexmedetomidine, are widely used as adjuvants during anesthesia for analgesic, sedative, sympatholytic, and cardiovascular stabilizing effects.
Aims:
We compared effects of clonidine and dexmedetomidine (as propofol adjuvants) on intra-operative hemodynamics, recovery time, and postoperative cognitive function impairment.
Subjects
and
Methods:
Forty-five American Society of Anesthesiologists I and II patients, scheduled for laparoscopic cholecystectomy were divided into three groups (
n
= 15). Group C patients received bolus of clonidine 3 μg/kg followed by a continuous infusion; Group D patients received dexemedetomidine 1 μg/kg and a continuous infusion; and Group P patients received a bolus of normal saline followed by an infusion. Intra-operative mean arterial pressure (MAP) and pulse rate (PR) were measured throughout the surgery. Bispectral index was maintained at 55 5 by titrating propofol infusion rate. The time between the interruption of anesthesia and eye opening (recovery time) was measured. Cognitive function was assessed using short mental status questionnaire at 15, 30, 45, and 60 min postoperatively.
Results:
The sympathetic response to laryngoscopy and extubation on MAP and PR were significantly reduced with the use of clonidine and dexmedetomidine (
P
< 0.05). The recovery was delayed (
P
< 0.05) with both the drug combinations and it was more pronounced with dexmedetomidine (
P
< 0.05). Dexmedetomidine group showed cognitive impairment in a postoperative period lasting up to an hour.
Conclusions:
When co-administered with propofol, both clonidine, and dexmedetomidine attenuate sympathetic response to laryngoscopy and extubation but cause delay in the recovery from anesthesia. Dexmedetomidine causes impairment of postoperative cognitive functions.

Visceral adipose tissue influences on coronary artery calcification at young and middle-age groups using computed tomography angiography
Rami M Abazid, M Obadah Kattea, Sawsan Sayed, Hanaa Saqqah, Mohammed Qintar, Osama A Smettei
July-September 2015, 5(3):83-88
DOI
:10.4103/2231-0770.160242
PMID
:26229760
Purpose:
The purpose of the study was to evaluate the impact of excessive visceral adipose tissue (VAT) on subclinical coronary atherosclerosis and coronary artery calcifications (CAC) in young and middle-age groups using multislice computed tomography.
Methods:
This study is a single center, cross-sectional study. Eligible patients (
n
= 159), who under the age of 61 years, with chest pain and mild to moderate probability to have coronary artery disease (CAD) were enrolled. Coronary calcium score and epicardial adipose tissue (EAT) were measured at the level of the left main coronary artery while VAT was measured at the level of the iliac crest.
Results:
The average age was (48 ± 8 years). The mean VAT was (38 ± 21 cm
2
) with no significant difference between men and women (38 ± 22 vs. 37 ± 19
P
= 0.8) respectively. Student's
t
-test analysis showed significantly higher VAT in patients with detectable CAC than patients with no CAC (48 ± 24 vs. 33 ± 18
P
= 0.00002), respectively. Univariate regression analysis showed that VAT and EAT, are strong predictor for CAC (hazard ratio [HR] 1.034, 95% confidence interval [CI: 1.016-1.052].
P
<0.001 and [HR] 1.344, 95% CI: [1.129-1.601]
P
= 0.001), respectively.
Conclusion:
Excessive VAT is significantly associated with positive CAC. VAT can strongly predict subclinical CAD in individuals at young and middle-age groups.

The recent advances in diagnostic pulmonary procedures have revolutionized the evaluation of abnormal thoracic findings including lung nodules and masses, mediastinal lymphadenopathy, and pleural diseases. Bronchoscopies with endobronchial ultrasonography and electromagnetic navigation are examples of new technology that has significantly improved the specificity and sensitivity of these procedures in diagnosis and staging of lung cancer without the need for more invasive procedures. This report describes the different diagnostic pulmonary interventions providing a description of the procedures, their indications, diagnostic yield and drawback.

Kirti Sharma, Naresh Kumar, Joshil Kumar Behera, Sushma Sood, Sibadatta Das, Harnam Singh Madan
July-September 2015, 5(3):79-82
DOI
:10.4103/2231-0770.160234
PMID
:26229759
Objectives:
The association of hypothyroidism with impairment of hearing is known to occur. It may be of any kind i. e., conductive, sensorineural or mixed. The aim of this study is to assess auditory pathway by brainstem auditory evoked potential (BAEP) in newly diagnosed patients of clinical hypothyroidism and healthy sex- and age-matched controls.
Materials and Methods:
The study included 25 healthy age- and sex-matched controls (Group I) and 25 patients of newly diagnosed clinical hypothyroidism (Group II). The recording was taken by using RMS EMG EP MK2 equipment.
Statistical Analysis Used:
Unpaired Student's t test.
Results:
There was a significant increase in wave IV (5.16 ± 0.85 ms) and wave V (6.17 ± 0.89 ms) latencies of right ear BAEP of Group II in comparison to wave IV (4.66 ± 0.39 ms) and wave V (5.49 ± 0.26 ms) of Group I. Wave V of left ear BAEP of Group II was also prolonged (6 ± 0.61 ms) in comparison to Group I (5.47 ± 0.35 ms). There was a significant difference in inter-peak latencies IPL I -V (4.44 ± 0.66 ms) and IPL III -V (2.2 ± 0.5 ms) of right ear BAEP of Group II in comparison to IPL I -V (3.94 ± 0.31 ms) and IPL III -V (1.84 ± 0.34 ms) of Group I. A significant prolongation was also found of IPL I -V (4.36 ± 0.59 ms) and IPL III -V (2.2 ± 0.42 ms) of left ear BAEP of Group II in comparison to IPL I -V (3.89 ± 0.3 ms) and IPL III -V (1.85 ± 0.3 ms) of Group I.
Conclusion:
Prolongation of wave IV and V along with inter-peak latencies in BAEP of both ears suggests that central auditory pathway is affected significantly in clinical hypothyroid patients.
