Abstract
BACKGROUND Laparoscopic surgery has changed the face of medical care forever. The benefits of laparoscopic open surgery have been demonstrated in virtually all major abdominal surgical procedures. Laparoscopy has introduced a new skill set that must be mastered and requires dedicated training. The teaching of laparoscopic operative skills in the clinical setting is constrained by the complexity of procedures, medicolegal and ethical concerns, fiscal and time limitations. This has created the need for formal training outside the operating room. Simulator-based training holds great promise in enhancing surgical education and providing a safe, cost-effective means for practicing techniques prior to their use in the operating room. METHODS The surgical residents of two batches were recruited for the study. The residents were randomized to either a group that received training on a simulator or a controlled group that did not receive the training or to a group that received training twice. RESULT The residents who received training on a simulator demonstrated better psychomotor skills in the operation theatre than those who did not. Training in simulator environment can contribute to the development of technical skills relevant to the performance of laparoscopic surgery in vivo. Training at regular intervals will benefit the residents in gaining significant improvement of their psychomotor skills. CONCLUSION Laparoscopic trainer is a promising tool for training in laparoscopic surgery.

Abstract
OBJECTIVE To enhance overall accuracy of medication lists by providing performance feedback and training to the healthcare team and increasing patient participation in the medication reconciliation process. METHODS This prospective study involved patients seen in four academic, ambulatory primary care internal medicine clinics. Before the interventions, baseline data were analysed, assessing completeness, correctness and accuracy of medication documentation in the electronic medical record. Interventions to provide performance feedback and training to the healthcare team, increase patient awareness and participation in the medication reconciliation process were implemented. Immediately after each intervention, a data collection was undertaken to assess the effectiveness of the intervention on the accuracy of individual medications and medication lists. RESULTS Completeness of medication lists improved from 20.4% to 50.4% (p<0.001). The incomplete documentation of medication lists was mostly because of lack of frequency (15.4%) and route (8.9%) for individual medications within a medication list. Correctness of medication lists improved from 23.1% to 37.7% (p = 0.087). The incorrectness in a medication list was mostly because of incorrect medications dose. Patient participation in the medication reconciliation process increased from 13.9% to 33% (p<0.001). The medication list accuracy improved from 11.5% to 29% (p = 0.014). CONCLUSION In this setting, it was helpful to engage the active participation of all members of the healthcare team and most importantly the patient to improve the accuracy of medication lists.

Abstract
Damage control is not a modern concept, but the application of this approach represents a new paradigm in surgery, borne out of a need to save patients with severe exsanguinating injuries. Definitive control and repair may be accomplished in the immediate post injury setting but the physiological derangement due to massive shock state resulting from the severe injury and the resuscitation that follows, often leads to a fully repaired but dead patient. The vicious triad of death in trauma, namely hypothermia, acidosis and coagulopathy should be tackled by initial abbreviated laparotomy, correction of physiological derangements and finally definitive repair of all injuries at second laparotomy. The concept needs a dedicated team effort with careful patient selection for achieving the optimal results.

Abstract
Clostridium perfringens has been reported as causing between 2-15% of all cases of antibiotic-associated diarrhoea (AAD), and may be diagnosed by detection of enterotoxin in faeces. A prospective study comprising 150 diarrhoeal patients and 100 non-diarrhoeal controls was undertaken to assess the incidence of C. perfringens-associated diarrhoea in an Indian hospital. Methods used included C. perfringens culture, reverse passive latex agglutination (RPLA) and enzyme-linked immunosorbent assay (ELISA) for detection of enterotoxin, and polymerase chain reaction (PCR) assay for the presence of enterotoxin gene. Attempts were made to type the isolates by multiplex PCR. Of the 150 diarrhoeal stool samples tested, 13 were culture positive. Of these, four were positive for C. perfringens enterotoxin by RPLA, two were positive by PCR and two were positive by RPLA and ELISA. Twenty-seven samples were positive for culture of C. perfringens in non-diarrhoeal controls but none were positive for enterotoxin either by RPLA or by PCR. The average incidence of C. perfringens AAD using these methods was 2.6%. Toxin typing showed that all the isolates belonged to type A. To conclude, the relatively low incidence of toxigenic C. perfringens suggests that enterotoxigenic C. perfringens is not a major cause of AAD in this population.

Abstract
The effect of pH on the antimicrobial activity of Melaleuca alternifolia essential oil formulations was studied. Microemulsions, liposomal dispersions, multiple emulsions and a colloidal bed of sterile clay were formulated using 5% w/w of tea tree oil. A number of formulations were prepared at various pH values (5.0, 5.5, 6.0, 6.5, and 7.0). Thermal stability studies showed that the formulations were stable for more than eight months. Agar dilution tests showed MICs of 1.0% v/v S. aureus and S. epidermidis. In the broth dilution test, MBC of the oil for P. acnes was 0.5% v/v. MIC and MBC values were comparable to those of non-formulated tea tree oil, indicating that tea tree oil retained its activity in the above-mentioned formulations. The microbiological evaluation showed that the formulations containing 5% w/w tea tree oil had a maximum effect at pH 5.5.

Abstract
The emergence of reduced susceptibility to ciprofloxacin among Salmonella enterica serotype Typhi and serotype Paratyphi A leading to clinical failure of treatment poses a great therapeutic challenge. The mechanism of fluoroquinolone resistance in clinical isolates of S. Typhi and S. Paratyphi A is not very well documented. The present study was carried out with the objective of molecular characterization of reduced quinolone susceptibility amongst the strains of S. Typhi and S. Paratyphi A isolated from the patients with enteric fever during January, 2000, to April, 2003, in a North Indian hospital. A total of 422 culture-positive cases of enteric fever were reported to the hospital during the period of study, of which S. Typhi was isolated from 350 cases and S. Paratyphi A from 72 cases. The antimicrobial susceptibility of these strains was determined by disk diffusion and agar dilution method according to NCCLS guidelines, and E-test method. A total of 140 randomly selected strains, isolated during the years 1993-1999, that were available from the laboratory stocks were also studied to compare with the present strains. To study the quinolone susceptibility, the strains were divided into nalidixic acid sensitive (NAS), nalidixic acid intermediate resistant, (NAI) and nalidixic acid resistant (NAR) on the basis of susceptibility to nalidixic acid. Clinical history was available from 174 patients, of which 93 needed hospitalization due to severe disease. Of these, 82 patients were infected with NAR strains and 22 patients had a documented evidence of clinical failure to ciprofloxacin therapy. The patients infected with NAR strains were younger and had a significantly longer duration of fever (p value < 0.05) than those infected with NAS strains. It was observed that the proportion of NAR strains increased gradually over the years. These strains had a significantly higher range of MIC of ciprofloxacin (0.023-1.0 microg/ml) as compared to the NAS strains (0.002-0.125 microg/ml) (p value < 0.05). The sequencing of quinolone resistance determining region (QRDR) of the gyrA gene showed the presence of mutation at either Ser 83 or at Asp 87 in all the NAR and NAI strains. None of the NAS strains had a mutation, suggesting that the gyrA gene mutation is sufficient to confer resistance to nalidixic acid and reduced susceptibility to ciprofloxacin. This mutation, although phenotypically expressed as decreased susceptibility to ciprofloxacin, goes undetected by the disk diffusion method using the present NCCLS guidelines. Hence, it can increase morbidity and mortality due to delay in appropriate antibiotic treatment.

Abstract
Although 50-70% of head and neck cancer patients in India receive radiotherapy (RT), radiation-related acute and late morbidities and their impact on quality of life (QOL) are infrequently reported. Acute and late radiation morbidities and QOL were assessed in a prospective longitudinal study of 45 patients with head and neck cancers receiving radical RT to a dose of 7000 cGy in conventional fractionation. Grade II acute morbidities experienced by the largest percent of the sample during the course of RT pertained to the mucosa (66.4%), salivary gland (84%), and oesophagus (53%). These morbidities led to an increase in the symptom scores of appetite loss (76.46), fatigue (65.75) and pain (44.77). This increase in the symptom scores consequently led to a significant decline in physical, social and emotional functioning as well as global health status score during the course of RT (p < 0.001). Scores improved after 1 month of RT but did not reach the pre-RT value. Future studies may consider correlating QOL assessment to significant patient and disease related parameters such as performance status, weight loss, stage and site of disease.

Abstract
Biodegradable dental films containing a combination of amoxycillin and metronidazole were prepared by a dispersion method. The aim of the present study was to determine the antimicrobial activity of this formulation against the pathogens which are commonly implicated in periodontal infections. Films showed sustained release in vitro for a period of 16 days. In situ release studies carried out using fresh bovine buccal mucosa in a flow through cell, showed that drug concentrations were maintained above MIC values for the entire period of the release studies. Samples from these studies were capable of inhibiting the growth of most of the test strains. The combination of amoxycillin and metronidazole using carrier polymer poly-L (lactide co-glycolide) not only showed an extended spectrum of antimicrobial activity but also showed a synergistic effect against Eubacterium limosum, which had earlier been reported resistant to metronidazole.

Abstract
Patients with hematological malignancies who are receiving chemotherapy suffer prolonged periods of neutropenia, which leads to a greater risk of infection and mortality. A prospective study was conduced to determine the incidence of bacteremia in patients of hematological malignancies over a 2-yr period. A total of 119 episodes of febrile neutropenia occurred among 96 consecutive patients, of which 35 episodes were associated with bacteremia. Forty-four percent of the isolated bacteria were Gram-positive aerobes and 46% were Gram-negative aerobes. Staphylococcus aureus, Enterococcus spp., and Escherichia coli were the most common isolates. Gram-negative bacteremia was associated with a higher mortality. Anaerobes accounted for 4.4% of all isolates. The episodes of anaerobic bacteremia were polymicrobial and had a fatal outcome. A high incidence of antimicrobial resistance among aerobic and anaerobic bacteria was also recorded. Compared to previous years, a shift from a predominating Gram-negative to a Gram-positive etiology was noted. The initial empiric antibiotic regimens should be based on a local knowledge of the most common causative microorganisms, their sensitivity pattern, and the outcome of bacteremia.

Abstract
AIMS Subtyping of Salmonella Paratyphi A isolates from India, Pakistan, Indonesia and Malaysia was carried out by pulsed-field gel electrophoresis (PFGE) to assess the extent of genetic diversity of these isolates from different endemic countries. METHODS AND RESULTS A total of 39 human isolates of Salmonella Paratyphi A from Pakistan, India, Indonesia and Malaysia were studied using PFGE analysis following digestion of chromosomal DNA with XbaI. Seven isolates from Pakistan were resistant to ampicillin, tetracycline and cotrimoxazole. It was noted that Salmonella Paratyphi A isolates obtained from outbreaks in India had limited genetic diversity and probably belonged to closely related clones. Significant genetic homogeneity was observed among antimicrobial-resistant isolates from Pakistan and antimicrobial-sensitive isolates from Pakistan and Indonesia, respectively. CONCLUSIONS PFGE was a useful subtyping technique to differentiate Salmonella Paratyphi A from different endemic countries. However, it fails to differentiate the antimicrobial-resistant and -sensitive strains. SIGNIFICANCE AND IMPACT OF THE STUDY The findings of the present study verify the usefulness of PFGE in characterizing and comparing strains of Salmonella Paratyphi A. Our study suggests that a limited number of clones are responsible for paratyphoid fever in these countries.
