Abstract
PURPOSE No approved targeted therapy for the treatment of patients with neuroblastoma RAS viral (v-ras) oncogene homolog (NRAS)-mutant melanoma is currently available. PATIENTS AND METHODS In this phase Ib escalation/expansion study (ClinicalTrials.gov identifier: NCT02974725), the safety, tolerability, and preliminary antitumor activity of naporafenib (LXH254), a BRAF/CRAF protein kinases inhibitor, were explored in combination with trametinib in patients with advanced/metastatic KRAS- or BRAF-mutant non-small-cell lung cancer (escalation arm) or NRAS-mutant melanoma (escalation and expansion arms). RESULTS Thirty-six and 30 patients were enrolled in escalation and expansion, respectively. During escalation, six patients reported grade ≥3 dose-limiting toxicities, including dermatitis acneiform (n = 2), maculopapular rash (n = 2), increased lipase (n = 1), and Stevens-Johnson syndrome (n = 1). The recommended doses for expansion were naporafenib 200 mg twice a day plus trametinib 1 mg once daily and naporafenib 400 mg twice a day plus trametinib 0.5 mg once daily. During expansion, all 30 patients experienced a treatment-related adverse event, the most common being rash (80%, n = 24), blood creatine phosphokinase increased, diarrhea, and nausea (30%, n = 9 each). In expansion, the objective response rate, median duration of response, and median progression-free survival were 46.7% (95% CI, 21.3 to 73.4; 7 of 15 patients), 3.75 (95% CI, 1.97 to not estimable [NE]) months, and 5.52 months, respectively, in patients treated with naporafenib 200 mg twice a day plus trametinib 1 mg once daily, and 13.3% (95% CI, 1.7 to 40.5; 2 of 15 patients), 3.75 (95% CI, 2.04 to NE) months, and 4.21 months, respectively, in patients treated with naporafenib 400 mg twice a day plus trametinib 0.5 mg once daily. CONCLUSION Naporafenib plus trametinib showed promising preliminary antitumor activity in patients with NRAS-mutant melanoma. Prophylactic strategies aimed to lower the incidence of skin-related events are under investigation.

Evidence of Antineutrinos from Distant Reactors Using Pure Water at SNO. PHYSICAL REVIEW LETTERS 2023; 130:091801. [PMID: 36930908 DOI: 10.1103/physrevlett.130.091801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Revised: 12/14/2022] [Accepted: 01/20/2023] [Indexed: 06/18/2023]
Abstract
The SNO+ Collaboration reports the first evidence of reactor antineutrinos in a Cherenkov detector. The nearest nuclear reactors are located 240 km away in Ontario, Canada. This analysis uses events with energies lower than in any previous analysis with a large water Cherenkov detector. Two analytical methods are used to distinguish reactor antineutrinos from background events in 190 days of data and yield consistent evidence for antineutrinos with a combined significance of 3.5σ.

Abstract
Abstract
Background: MAPK pathway dysregulation is a characteristic molecular abnormality of melanoma. NRAS mutations in melanoma lead to constitutive MAPK activation and subsequent MEK and ERK activation. Inhibiting the pathway with a combination of BRAF/CRAF and MEK inhibitors (LXH254 and TMT, respectively) has demonstrated synergistic activity in preclinical models of NRAS-mutant melanoma.
Methods: We report data from an open-label, Phase Ib study (NCT02974725), that tested LXH254 + TMT combination in a dose-escalation (ESC) part in pts with KRAS- or BRAF-mutant NSCLC or NRAS-mutant melanoma and in a dose-expansion (EXP) part in NRAS-mutant melanoma pts. In ESC, five dose levels were explored: LXH254 200 mg twice daily (BID) + TMT (1 mg or 0.5 mg) daily (QD); LXH254 400 mg BID + TMT (1 mg or 0.5 mg) QD; LXH254 400 mg BID + TMT 1 mg (QD, 2 wk on/2 wk off). Primary objectives were to evaluate safety and tolerability, and determine the recommended dose for expansion (RDE). Secondary objectives were to characterize pharmacokinetics and pharmacodynamics of LXH254 + TMT, and evaluate antitumor activity.
Results: As of Dec 9, 2021, 36 and 30 pts were enrolled in ESC and EXP, respectively; median age was 63.5 and 69 y, respectively. Pts in ESC and EXP received a median of 3 (range: 1-6) and 2 (range: 1-7) prior treatments, respectively, including IO (ESC: 88.9% pts; EXP: 96.7% pts). All pts from ESC and 24 pts from EXP discontinued, mainly due to progressive disease (61.1% and 60%, respectively); 6 pts were ongoing in EXP at data cut-off. In ESC, Grade ≥3 (G≥3) DLTs were reported in 6 pts: dermatitis acneiform (n=2), maculopapular rash (n=2), increased lipase (n=1), and Stevens-Johnson syndrome (n=1). The RDEs were LXH254 200 mg BID + TMT 1 mg QD and LXH254 400 mg BID + TMT 0.5 mg QD. Treatment-related adverse events (TRAEs) were reported in 34 pts (94.4%) in ESC and all pts in EXP. G≥3 TRAEs in ESC and EXP were experienced by 19 (52.8%) and 24 (80%) pts, respectively; the most common being rash or dermatitis acneiform (13.9% each) in ESC and rash (33.3%) in EXP. One fatal TRAE (hypovolemic shock) was reported in the LXH254 400 mg BID + TMT 0.5 mg QD group. The ORR in EXP was 46.7% (7 pts; 95% CI: 21.3-73.4) for LXH254 200 mg BID + TMT 1 mg QD and 13.3% (2 pts; 95% CI: 1.7-40.5) for LXH254 400 mg BID + TMT 0.5 mg QD; overall in EXP, 9 pts (30%) achieved PR and 13 pts (43.3%) reported SD. In EXP the median DOR was 3.8 months (95% CI: 2.6-7.4). Exposures of LXH254 (200 mg or 400 mg BID) + TMT (0.5 mg or 1 mg QD) vs LXH254 single agent were comparable, indicating no apparent LXH254-TMT interactions. Limited paired tumor biopsy data (n=8) showed substantial MAPK pathway inhibition (DUSP6).
Conclusions: LXH254 in combination with TMT has shown preliminary antitumor activity in the pretreated, NRAS-mutant melanoma population. A Phase II trial of LXH254 combinations in pts with pretreated BRAF- or NRAS-mutant melanoma is currently ongoing (NCT04417621).

Abstract
BACKGROUND: Chronic pain after inguinal hernia repair is a common complication. This study compared the difference between Desarda repair and Lichtenstein repair for inguinal hernia in chronic groin pain. METHODS: One hundred patients with unilateral uncomplicated inguinal hernia were randomised to either Desarda repair (n = 50) or Lichtenstein repair (n = 50) under local anaesthesia and were evaluated for pain postoperatively. Operative time, surgical complications, time to return to normal gait and work, and overall patient satisfaction were recorded. The patient was blinded to the procedure. Any pain at three months (numerical rating scale 1 or more) was considered chronic pain. RESULTS: Mean operation time was approximately 5 minutes less for Desarda (p = 0.33). There was no significant difference in terms of pain level postoperatively between Lichtenstein and Desarda groups. Twenty-two (44%) patients in the Lichtenstein group had chronic pain, and twenty-one (45.7%) patients had chronic pain in the Desarda group (p = 0.871). No significant difference was observed in haematoma formation, wound infection, recurrence rate, seroma, or foreign body sensation. The mean time for patients to return to normal gait was approximately 0.5 day earlier for the Desarda group (p = 0.29). The mean time for patients to return to normal work was comparable (p = 0.99). Desarda group had a slightly higher satisfaction rate than the Lichtenstein group (9.1%). CONCLUSION: Desarda repair is not inferior to Lichtenstein repair in the short-term concerning complications or pain.

Abstract
AIM Prison is an especially difficult environment for promoting oral health and leads to the exacerbation of unhealthy behaviors. This study set out to assess the impact of incarceration on nutritional status and oral health among the male prison inmates of Central Jail of Jaipur city, Rajasthan, India. MATERIAL AND METHOD A cross sectional study was conducted among 181 male inmates. Dental caries and periodontal status were assessed by using modified the Decayed Missing Filled Teeth (DMFT) index and Community Periodontal Index (CPI) and Loss of Attachment (LOA) index as per the WHO methodology 1997. Nutritional status was assessed by Body Mass Index (BMI) and weight (kg)/height (m2). RESULTS Out of 181 inmates, 141 (77.90%) had normal BMI. The majority (n=128, 70.70%) of inmates were incarcerated for less than 6 years. A significant difference (P<0.05) was found between age and periodontal status. A significant difference was observed (P<0.05) in the CPI score 3 and LOA 0 and 1 score. However, no significant difference (P>0.05) was observed in DMFT and period of incarceration. Age was the significant (P<0.001) risk factor for CPI and LOA. DISCUSSION Dental caries and periodontal health deteriorates with age and period of incarceration. Oral hygiene maintenance along with comprehensive oral care can be accomplished by establishing dental care facilities in prisons.

Abstract
Background: This analysis evaluated patient-reported outcomes (PROs) to assess health-related quality of life (HRQoL) in the phase III MONALEESA-7 trial, which previously demonstrated improvements in progression-free survival (PFS) and overall survival (OS) with ribociclib (cyclin-dependent kinase 4/6 inhibitor) + endocrine therapy (ET) compared with placebo + ET in pre- and perimenopausal patients with hormone-receptor-positive, HER2-negative (HR+/HER2−) advanced breast cancer (ABC). Methods: The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life questionnaire C30 (QLQ-C30) and the EQ-5D-5L were used to evaluate HRQoL. Results: EORTC QLQ-C30 assessments were evaluable for 335 patients in the ribociclib arm and 337 patients in the placebo arm. Adherence rates at baseline and ⩾1 postbaseline time point were 90% and 83%, respectively. Patients treated with ribociclib + ET had a longer time to deterioration (TTD) ⩾ 10% in global HRQoL {hazard ratio (HR), 0.67 [95% confidence interval (CI), 0.52–0.86]}. TTD ⩾ 10% in global HRQoL was delayed in ribociclib-treated patients without versus with disease progression [HR, 0.31 (95% CI, 0.21–0.48)]. TTD ⩾ 10% in pain was longer with ribociclib + ET than with placebo + ET [HR, 0.65 (95% CI, 0.45–0.92)]. Patients who received a nonsteroidal aromatase inhibitor experienced similar benefits with ribociclib versus placebo in global HRQoL and pain. Conclusion: HRQoL was maintained longer in patients who received ribociclib + ET versus placebo + ET. These data, combined with previously reported improvements in PFS and OS, support a strong clinical benefit-to-risk ratio with ribociclib-based treatment in pre- and perimenopausal patients with HR+/HER2− ABC.

Abstract
1054 Background: In the Phase III ML-3 (NCT02422615) and ML-7 (NCT02278120) trials, RIB + ET demonstrated a significant OS benefit (ML-3: HR, 0.72, P = 0.00455; ML-7: HR, 0.71, P = 0.00973) over placebo (PBO) + ET in pts with HR+/HER2- ABC (Im et al. N Engl J Med. 2019; Slamon et al. N Engl J Med. 2019). The presence of visceral mets generally portends a poor prognosis, which is especially poor in pts with liver mets (He et al. Ann Oncol. 2019). Here we report OS in pts with visceral mets with a focus on those with liver mets in ML-3 and ML-7. Methods: In ML-3, postmenopausal pts were randomized 2:1 to receive RIB + fulvestrant (FUL) or PBO + FUL as first- (1L) or second-line (2L) treatment. In ML-7, premenopausal pts were randomized 1:1 to receive RIB + ET or PBO + ET (this analysis included only pts who received an NSAI as ET partner to match approved indication). Results: Visceral mets were identified in 293 pts (60.5%) in the RIB arm and 147 (60.7%) in the PBO arm in ML-3 and 150 (44.8%) and 142 pts (42.1%), respectively, in ML-7. In ML-3, the median age of pts with visceral mets was 63 and 65 years in the RIB and PBO arms, and in ML-7 it was 42.5 and 45.0 years, respectively. In ML-3, 214 pts with visceral mets received 1L therapy (RIB, n = 137; PBO, n = 77), while 219 pts received 2L therapy or had early relapse (RIB, n = 151; PBO, n = 68). Lung and liver were the most common sites of visceral mets for pts in ML-3 (49.8% and 44.8%, respectively) and ML-7 (51.4% and 58.2%, respectively). OS HRs in pts with visceral mets were consistent with the benefit in the overall pt populations and suggested a particularly substantial OS benefit in pts with liver mets (HR for liver mets group in ML-3, 0.629 [95% CI, 0.421-0.942]; HR in ML-7, 0.531 [95% CI, 0.321-0.877]; Table). No new safety signals were observed. Conclusions: Approximately half of the pts in ML-3 and ML-7 had visceral mets. The OS data in these pts are consistent with the benefit observed with RIB in the overall populations of each trial. In pts with liver mets, a group with an especially poor prognosis, RIB + ET demonstrated a substantial OS benefit compared with PBO + ET. Clinical trial information: NCT02422615; NCT02278120 .

Abstract
AIM The aim of this cross-sectional study is to investigate the prevalence and related risk factors of early childhood caries (ECC) in preschool children of district Mandi, Himachal Pradesh, India. MATERIALS AND METHODS A total sample of 2859 children aged between 2 and 6 years were selected from various parts of district Mandi. The status of dental caries and decayed missing and filled teeth (DMFT) score was recorded. RESULTS ECC increased significantly with age. Boys had significantly higher caries prevalence and mean DMFT score as compared to girls. Children who belonged to low socioeconomic group showed higher caries prevalence and mean DMFT score. Children aged 3-6 years who brushed their teeth twice daily had the least prevalence of dental caries as well as DMFT score when compared to children with one time and no brushing. CONCLUSION The early identification of poor oral hygiene and improper feeding habits should be considered in preventive health promotion in low socioeconomic communities of district Mandi, Himachal Pradesh.

Abstract
Abstract
Background: Younger patients (pts) with breast cancer may experience more aggressive disease and are more likely to die from their cancer vs older pts. In the Phase III MONALEESA-7 study (NCT02278120), the addition of ribociclib (RIB; cyclin-dependent kinase 4/6 inhibitor) to a non-steroidal aromatase inhibitor (NSAI) or tamoxifen (TAM) + goserelin significantly prolonged progression-free survival (PFS) in premenopausal women with hormone receptor-positive (HR+), HER2-negative (HER2–) advanced breast cancer (ABC; hazard ratio 0.553; p<0.0001). RIB treatment benefit was observed irrespective of endocrine partner (NSAI or TAM). Here we report results from a MONALEESA-7 subgroup analysis in pts aged <40 yrs and ≥40 yrs who received RIB or placebo (PBO) in combination with an NSAI + goserelin.
Methods: Pre- or perimenopausal women with HR+, HER2– ABC who had received no prior endocrine therapy and ≤1 line of chemotherapy for ABC were enrolled. Of the 672 pts randomized, 495 (74%) received RIB (600 mg/day, 3-weeks-on/1-week-off) or PBO + an NSAI (letrozole [2.5 mg/day] or anastrozole [1 mg/day]) and goserelin (3.6 mg every 28 days). The primary endpoint was locally assessed PFS; secondary endpoints included overall response rate (ORR), clinical benefit rate (CBR), and safety. A prespecified subgroup analysis was performed in pts aged <40 yrs and ≥40 yrs.
Results: A total of 144 pts were aged <40 yrs (RIB vs PBO arm: 78 vs 66) and 351 were aged ≥40 yrs (170 vs 181). As of August 20, 2017, in the RIB vs PBO arms, treatment was ongoing in 50% vs 23% of pts aged <40 yrs and 54% vs 43% of pts aged ≥40 yrs; disease progression was the most common reason for treatment discontinuation (<40 yrs: 37% vs 68%; ≥40 yrs: 35% vs 44%). Median PFS was prolonged in the RIB vs PBO arms both in pts aged <40 yrs (not reached vs 10.8 months; hazard ratio 0.435; 95% confidence interval [CI] 0.276–0.686) and in pts aged ≥40 yrs (27.5 vs 19.1 months; hazard ratio 0.625; 95% CI 0.449–0.870). In pts with measurable disease, the ORR (RIB vs PBO arm) was 49% vs 32% in pts aged <40 yrs and 51% vs 38% in pts aged ≥40 yrs; CBR was 81% vs 61% and 82% vs 65%, respectively. The most common Grade 3 adverse events (AEs; ≥5% of pts in either arm; RIB vs PBO arm) were neutropenia (<40 yrs: 47% vs 5%; ≥40 yrs: 58% vs 3%), leukopenia (<40 yrs: 18% vs 2%; ≥40 yrs: 14% vs 1%), diarrhea (<40 yrs: 5% vs 0; ≥40 yrs: 1% vs 0), and increased alanine aminotransferase (<40 yrs: 4% vs 2%; ≥40 yrs: 5% vs 1%); neutropenia was the only Grade 4 AE occurring in ≥5% of pts in either arm (<40 yrs: 15% vs 0; ≥40 yrs: 8% vs 1%). New post-baseline QTcF >480 ms (RIB vs PBO arm) occurred in 3% vs 2% of pts aged <40 yrs and 7% vs 1% of pts aged ≥40 yrs.
Conclusions: Consistent treatment benefit was observed with RIB + NSAI vs PBO + NSAI in premenopausal women with HR+, HER2– ABC irrespective of age. RIB + NSAI had a manageable safety profile in pts aged <40 yrs and in those aged ≥40 yrs, with a safety profile similar to that observed in the full study population.

Abstract
Background: Patients (pts) with advanced breast cancer (ABC) who present with visceral metastases (mets) have a poorer prognosis vs pts with non-visceral disease. In the Phase III MONALEESA (ML) trials, ribociclib (RIB) + endocrine therapy (ET) prolonged progression-free survival (PFS) vs placebo (PBO) + ET in hormone receptor-positive (HR+), HER2-negative (HER2–) ABC. Here we show data for pts with and without visceral mets from the ML-2, -3, and -7 trials.
Methods: Data were collated from 3 trials in HR+, HER2– ABC: in ML-2 (NCT01958021; data cutoff [DCO] Jan 2/4, 2017), postmenopausal pts (no prior ET for ABC) received RIB or PBO + letrozole; in ML-3 (NCT02422615; DCO Nov 3, 2017), postmenopausal pts (no prior ET for ABC subgroup only) received RIB or PBO + fulvestrant; in ML-7 (NCT02278120; DCO Aug 20, 2017), premenopausal pts (no prior ET and ≤1 chemotherapy for ABC) received RIB or PBO + goserelin + anastrozole/letrozole. Endpoints; primary: local PFS; secondary: overall response rate (ORR), clinical benefit rate (CBR), safety.
Results: Of all 820 pts treated with RIB + ET, 484 (59%) had visceral mets (ML-2 197/334; ML-3 137/238; ML-7 150/248); of all 710 pts treated with PBO + ET, 416 (59%) had visceral mets (ML-2 196/334; ML-3 77/129; ML-7 143/247). Median PFS was prolonged for RIB vs PBO in pts with and without visceral mets (Table). ORR and CBR were also higher for RIB vs PBO in pts with and without visceral mets. The most common (≥10% of pts in any arm) Grade [G] 3 and 4 adverse events (AEs) for each trial are shown in the table; no G4 AEs occurred in ≥10% of pts in ML-3.

Abstract
The aim of this study is to compare the treatment effectiveness of botulinum toxin type A (BTX-A) and phenol blocks in the management of lower limb spasticity and to measure improvement in gross motor functional outcome in children with cerebral palsy (CP). This is a hospital-based prospective, noncontrolled randomized study that took place in a tertiary care center. A total of 61 ambulatory children with CP spastic diplegia, aged from 4 to 10 years, were randomly divided into two groups and included in this study. Twenty-eight children with CP received BTX-A injections and 33 received phenol motor point blocks. The measures performed were as follows: outcome assessment spasticity by the Modified Ashworth scale (MAS), active range of motion (AROM) of lower limb joint by goniometer, and functional improvement by Gross Motor Function Measures (GMFM). Postinjection follow-up done at 2, 6, 12, 24, and 48 weeks. Significant improvement in reduction of spasticity, increased AROM of all joints of lower limbs, and improvement in functional outcome were observed in CP with spastic diplegia after BTX-A injections as compared with the phenol motor point block group. There was no significant side effect after BTX-A injections as compared with phenol injections. BTX-A injections showed superior treatment effects in the reduction of spasticity and improvement in AROM and functional outcome measures with spastic diplegia as compared with phenol blocks. BTX-A injections also revealed fewer clinical side effects and were well tolerated by children with CP.

Abstract
BACKGROUND The Serratus anterior muscle plane (SAP) block has recently been described for the purpose of perioperative pain management following cases of trauma and breast surgery. It might prove a safer alternative to the other regional thoracic paravertebral and central neuraxial blockade techniques. There are no descriptive cadaveric studies in the pre-existing literature to delineate the anatomical plane for this novel technique. The main objectives for our study were to examine the location of the Serratus anterior muscle belly, assess the efficacy of achieving adequate delineation of the muscle plane utilising ultrasound imaging with agitated water as the contrast agent, and finally, to observe the extent of the cepahlo-caudal spread of the injectate in the SAP. MATERIALS AND METHODS Seven cadavers were studied. 20 mls of saline was injected into posterior axillary line (PAL) at the level of the 4-5(th) rib under ultrasound guidance. This was followed by injection of 10 mls of water with air (8 mls water and 2 mls of air). The presence of hyperechoic air bubbles in the fluid distended SAP (hypoechoic) area demonstrated the spread of water and air. RESULTS In 36% of cadavers, fully formed Serratus Anterior muscle belly was identified at the midaxillary line (MAL), 14% in PAL, and remaining 50% between PAL and MAL. The lower most limit of air-water spread was identified at the subcostal margin. Cephalad spread of contrast was noted in 2(nd) intercostal space ICS (7%), 3(rd) ICS (71%), and 4(th) ICS (22%). CONCLUSION This study describes that the serratus anterior muscle is well-formed near the PAL and the injectate spread can be determined with the help of agitated water contrast on ultrasound. Furthermore, there was variability in the cephalad spread of the injectate.

Abstract
Gitelman's syndrome is an autosomal recessive disorder characterized by hypokalemic metabolic alkalosis, hypokalemia, hypomagnesaemia, hypocalciuria, hyperreninemia and without hypertension. Gitelman's syndrome is caused by mutations of the SLC12A3 gene, which encodes the Na/Cl co-transporter (NCCT) in the distal convoluted tubule. Majority of cases manifest during adolescence or adulthood and growth retardation is not the common feature. We report a rare presentation of Gitelman's syndrome in a four-year-old boy with growth retardation.

Abstract
INTRODUCTION WHONET is a freely downloadable, Windows-based database software which is used for the management and analysis of microbiology data, with a special focus on the analysis of antimicrobial susceptibility test results. Urinary Tract Infections (UTI) are a common medical problem and they are responsible for notable morbidity among young and sexually active women. OBJECTIVES The major objective of this study was the utilization and application of the WHONET program for the Antimicrobial Resistance (AMR) surveillance of uropathogens. METHODS A total of 3209 urine samples were collected from patients who visited Manipal Teaching Hospital with a clinical suspicion of UTI, during December 2010 to July 2011. The isolation and characterization of the isolates were done by conventional methods. Antimicrobial Susceptibility Testing (AST) was performed by Kirby Bauer's disc diffusion method. The data entry and analysis were done by using the WHONET 5.6 software. RESULTS Out of the 3209 specimens, 497 bacterial isolates were obtained and they were subjected to AST. Escherichia coli (66.2%) was the commonest bacterial isolate, followed by Enterococcus species (9.3%), Staphylococcus aureus (5.0%), and Klebsiella pneumoniae (4.2%). Among the gram-negative enteric bacilli, a high prevalence of resistance was observed against ampicillin and ciprofloxacin. The gram negative nonfermenters exhibited a high degree of resistance to ceftazidime. Staphylococcus species. showed a moderately high resistance to co-trimoxazole. One isolate was Vancomycin Resistant Enterococci (VRE). CONCLUSION This study, a first of its kind which was done in Nepal, was carried out by using the WHONET software to monitor, analyze and share the antimicrobial susceptibility data at various levels. This study was also aimed at building a surveillance network in Nepal, with the National Public Health Laboratory, Nepal, acting as a nodal centre. This would help in the formulation of antibiotic policies and in identifying hospital and community outbreaks at the nodal centre, as well as in sharing information with the clinicians at the local level.

Abstract
PURPOSE Klebsiella pneumoniae is considered an important pathogen causing nosocomial and community-acquired infections and is often associated with the production of extended-spectrum beta-lactamases (ESBL) belonging to SHV and CTX-M families, which are frequently described as a part of complex integrons, facilitate their horizontal transfer to other related as well as unrelated microbes. The present study was undertaken to investigate the occurrence and characterization of integrons among K pneumoniae isolates producing ESBL in a tertiary referral hospital. MATERIALS AND METHODS A total of 136 clinical isolates of K pneumoniae were investigated for the presence of ESBL. Their ESBL genes were characterized by multiplex polymerase chain reaction (PCR). Integrase gene PCR was performed to detect the presence of integron. The isolates were further typed by random amplification of polymorphic DNA (RAPD). RESULT Out of 136 K pneumoniae isolates, 63 (46%) were confirmed to be ESBL producers. SHV (68%) and CTX-M (67%) ESBL genes were the most common in our study. Of the 63 ESBL-positive isolates, 58 (92%) strains carried integrons; 52 strains (82%) carried only class 1 integron, whereas 6 (9%) isolates harboured both class 2 integrons and the class 1 gene. However, in ESBL negatives, only 29 (40%) strains were positive for class 1 integron and none for class 2 integron. CONCLUSION The presence of class 2 integron amongst ESBL-producing K pneumoniae is being described for the first time in this part of the world. The findings of this study strongly suggest that integrons have a role in the dissemination of ESBL-mediated resistance among the nosocomial isolates of K pneumonia.

Abstract
BACKGROUND Antibiotic prophylaxis is routinely administered in laparoscopic cholecystetomy but its role is debatable. METHODS From January 2004 to August 2008, 417 patients were randomized into 208 in antibiotic group (AG) and 209 in non antibiotic group (NAG). AG received one dose each of injection ciprofloxacin (200 mg) and metronidazole (500mg) preoperatively. NAG was given only intravenous fluids. Besides routine care, all underwent abdominal sonography and liver function tests at least once during the 30 postoperative days. RESULT Age, sex and co-morbidity distribution were similar in both the groups. One patient who was on weekly 5mg methotraxate (NAG) had erythema around umbilical port. Other three having umbilical discharge recovered without antibiotics. Nine patients had subhepatic collection (5 AG and 4 NAG). One from NAG underwent re-laparoscopy and drainage. Ten patients had fever. Two from AG had basal lung collapse and were given antibiotics. CONCLUSION Antibiotic prophylaxis is not needed for laparoscopic cholecystectomy.

Abstract
Emergence of extended spectrum beta lactamases (ESBLs) producing strains of gram negative bacteria, as one of the leading cause of septicaemia often complicates the clinical and therapeutic outcome. The present study was undertaken to investigate the prevalence of ESBLs in bacteria isolated from neonatal septicaemic cases along with their antimicrobial sensitivity pattern. Blood samples were collected from 243 suspected cases of neonatal septicaemia. Apart from susceptibility testing, all the gram negative isolates were subjected to phenotypic tests for ESBL production. Amongst the positive test samples (n = 115), 84 were gram negative rods. ESBL was detected in 26 (32%) isolates. Results indicate that routine ESBL detection should be made imperative and empirical use of third generation cephalosporins must be discouraged.

Abstract
Acinetobacter species are emerging as an important nosocomial pathogen. Multidrug-resistant Acinetobacter spp. has limited the option for effective treatment. Although carbapenems are effective for the treatment of such infections, resistance to this drug has recently been reported. This study was undertaken to assess resistance to carbapenem in clinical isolates of Acinetobacter spp. from hospitalized patients by both disc-diffusion and minimum inhibitory concentration (MIC) methods. All clinical samples from suspected cases of nosocomial infections were processed, and 265 isolates were identified as Acinetobacter species. These isolates were tested for antibiotic resistance by the disc-diffusion method with 14 antimicrobials, including meropenem and imipenem. Thereafter, all Acinetobacter species were subjected to MIC for meropenem. More than 80% resistance to second- and third-generation cephalosporins, aminoglycosides, and quinolones was recorded. Thirty percent of the strains were resistant to cefoperazone/sulbactam. Resistance to meropenem was observed in 6.4% of Acinetobacter spp. while 8.3% of the isolates showed intermediate resistance detected by MIC. All carbapenem-resistant/intermediate strains were also resistant to other (>10) antibiotics tested by the disc-diffusion method. The rising trend of resistance to carbapenem poses an alarming threat to the treatment for such infections. Regular monitoring, judicious prescription, and early detection of resistance to carbapenem are necessary to check further dissemination of drug resistance in Acinetobacter spp.

Abstract
Quantitative trait loci (QTL) analysis was conducted for pre-harvest sprouting tolerance (PHST) in bread wheat for a solitary chromosome 3A, which was shown to be important for this trait in earlier studies. An inter-varietal mapping population in the form of recombinant inbred lines (RILs) developed from a cross between SPR8198 (a PHS tolerant genotype) and HD2329 (a PHS susceptible cultivar) was used for this purpose. The parents and the RIL population were grown in six different environments and the data on PHS were collected in each case. A framework linkage map of chromosome 3A with 13 markers was prepared and used for QTL analysis. A major QTL (QPhs.ccsu-3A.1) was detected on 3AL at a genetic distance of approximately 183 cM from centromere, the length of the map being 279.1 cM. The QTL explained 24.68% to 35.21% variation in individual environments and 78.03% of the variation across the environments (pooled data). The results of the present study are significant on two counts. Firstly, the detected QTL is a major QTL, explaining up to 78.03% of the variation and, secondly, the QTL showed up in all the six environments and also with the pooled data, which is rather rare in QTL analysis. The positive additive effects in the present study suggest that a superior allele of the QTL is available in the superior parent (SPR8198), which can be used for marker-aided selection for the transfer of this QTL allele to obtain PHS-tolerant progeny. It has also been shown that the red-coloured grain of PHS tolerant parent is not associated with the QTL for PHST identified during the present study, suggesting that PHS tolerant white-grained cultivars can be developed.

Abstract
Impact of temperature related seasonal changes in density of Golgi complex were studied in brain, heart and intestine of the freshwater catfish, Clarias batrachus (Linnaeus). The density of Golgi complex was more in these organs of the fish acclimatized to a lower temperature (20 degrees C) than that to a higher temperature (29 degrees C). This suggests that lower temperature induces secretory activity in cells to cope up with the changes in surrounding environment. It could be a kind of histophysiological adaptation in poikilothermic animal.

Abstract
Widespread external and internal changes in body morphology have long been known to be hallmarks of the process of metamorphosis. However, more subtle changes, particularly at the molecular level, are only now beginning to be understood. A number of transcription factors have recently been shown to alter expression either in levels of message or in isoforms expressed. In this article, we describe a dramatic increase in the expression of the homeobox gene HoxA5 in the heart and aorta of the Mexican axolotl Ambystoma mexicanum during the process of thyroxin-induced metamorphosis. Immunohistochemical analysis with anti-HoxA5 antibody in thyroxin-induced metamorphosing animals showed a pattern of expression of HoxA5 comparable to that in spontaneously metamorphosing animals. Further, by in situ hybridization, we were able to show significant qualitative differences in the expression of this gene within the heart. Maximum HoxA5 expression occurred at the midpoint of metamorphosis in the myocardium, whereas the hearts of completely metamorphosed animals had the highest levels of expression in the epicardium and endocardium. In the aorta, smooth-muscle cells of the tunica media as well as cells of the tunica adventitia had an increase in expression of HoxA5 with thyroxin-induced metamorphosis. HoxA5 expression significantly changed in cells of the aorta and ventricle with treatment by thyroid hormone. HoxA5, a positive regulator of p53, may be involved with the apoptotic pathway in heart remodeling during amphibian metamorphosis.

Abstract
Bronchobiliary fistula is defined as the passage of bile in the bronchi and in the sputum (bilioptysis). This rare disorder is associated with significant morbidity. Authors review the anaesthetic management of bronchobiliary fistula and recommend the use of double lumen endotracheal tube even in cases with a closed/sealed bronchobiliary fistula.
