ERCP practice at a tertiary care hospital in Kashmir, North India: a large single-center cross-sectional study with focus on quality indicators, success rate, and indications.

Endoscopic retrograde cholangiopancreatography (ERCP) is the most technically demanding endoscopic procedure with significant adverse events that mandate appropriate training, competence and careful decision-making. The American Society for Gastrointestinal Endoscopy (ASGE) and the European Society of Gastrointestinal Endoscopy (ESGE) updated a list of quality indicators and performance measures for pancreatobiliary endoscopy. Nevertheless, real-life data are scarce, especially from developing countries. The study aimed to assess overall quality, procedural success, and indications of ERCP at our center. Methods: An audit of our endoscopy center at the start of the study for quality and performance indicators and a retrospective analysis of the 4 years of the prospectively maintained data of patients who underwent ERCP regarding procedural success and indications was done. Results: The study showed that ERCP is performed by meeting good quality standards, but structured training, sedation practice, and microbiological surveillance are subpar. A total of 3544 procedures were carried out with successful cannulation of the naive papilla in 93%, with 60% of procedures carried out on females, 80.5% of procedures done for benign diseases, and 19.5% on suspected or proven malignancy (47% men and 53% women) with perihilar obstruction being commonest in both sexes (32-33%) followed by carcinoma gallbladder in women (21%) and distal cholangiocarcinoma in men (27%). Among benign diseases (2711), 12% had benign pancreatic diseases, and 64.8% had common bile duct (CBD) stones, with 31% of CBD stones requiring more than one session for clearance. Conclusion: ERCP at our center is performed by meeting quality standards and by competent endoscopists with good procedural success. Improving sedation strategies, microbiological surveillance, and training programs remains an unmet need.

Predictors of Rebleeding in Non-variceal Upper Gastrointestinal Bleeding of Peptic Ulcer Etiology in Kashmiri Population.

Background Upper gastrointestinal bleeding (UGIB) represents a substantial clinical and economic burden and rebleeding is one of the most important predictors of morbidity and mortality. Identifying patients who are likely to rebleed is a critical component of effectively managing patients with bleeding peptic ulcers. So, the study was undertaken to look for predictors of rebleeding in patients with bleeding peptic ulcers and try to find out the new scoring system to predict rebleeding in our population. Material and methods A retrospective analysis of prospectively maintained hospital data of UGIB patients was done and 480 patients of endoscopically documented peptic ulcers whose complete data was available were taken for study. Results Among the studied patients, men constituted 84.6%, and most of the patients were in the third to sixth decade of life with a mean age of 40.9±15.9 years, 76% were from rural areas. Only males with a mean age of 38.4±19.8 rebled with a rebleeding rate of 2.9% only. Half of the patients who rebled were in shock at the time of presentation. Those who rebled received more units of blood transfusion (mean 3±1.8), had a large mean ulcer size of Forest class IIa and IIb and epinephrine injection monotherapy group with varied statistical significance. Among rebleeders (n=14), eight patients were managed by a second endoscopic therapy, and six (42.8%) rebleeders and 1.25% of patients in total needed surgery. Two patients ultimately died giving overall mortality of 0.4% and mortality of 14.3% among rebleeders. Conclusion Our study found a very low rebleeding rate and mortality which could be explained by a young population with fewer co-morbidities and better response to proton pump inhibitor therapy. The significant parameters related to rebleeding were shock at presentation, degree of smoking, units of blood transfused, ulcer size, and high-risk endoscopic stigmata.

CTX-M-15 Positive Escherichia coli and Klebsiella pneumoniae Outbreak in the Neonatal Intensive Care Unit of a Maternity Hospital in Ha'il, Saudi Arabia.

OBJECTIVE: The aim of this study was to retrospectively characterize E. coli and K. pneumoniae isolates obtained from neonates during a suspected NICU outbreak of infection in Ha'il, Saudi Arabia during a period of one month (April 2014). METHODS: Antibiotic susceptibility patterns, molecular characterization for antibiotic-resistant genes (blaTEM, blaSHV, and blaCTX-M), and genotyping by PFGE and MLST were performed. RESULTS: A total of 24 E. coli and 48 K. pneumoniae isolates were cultured from neonates that had been admitted to the NICU. Among E. coli, the majority of isolates (19/24) were ESBL-positive and all of these nineteen (100%) harbored the CTX-M-15 gene. A total of 15% (3/19) were co-producers of CTX-M-15 and SHV-12, and 68.4% (13/19) were co-producers of CTX-M-15 and TEM-1. Among K. pneumoniae isolates, 87.5% (42/48) were ESBL positive with 92.85% (39/42) of these isolates containing the CTX-M-15 gene. A total of 97% (38/39) of K. pneumoniae were co-producers of CTX-M-15 and SHV-12, and 88% (37/42) were positive for TEM-1. Furthermore, 85.7% (36/42) K. pneumoniae were co-producers of CTX-M-15 and TEM-1. The majority of E. coli isolates (18/19 isolates) were grouped into two genetic clusters by pulsed field gel electrophoresis (PFGE) and all the isolates were found to be ST-131 type. In contrast, K. pneumoniae (31/42) isolates belonged to a single genotypic lineage, and all (100%) isolates belonged to the ST-14 type. CONCLUSION: This is the first report of CTX-M-15-positive, ESBL E. coli, and K. pneumoniae isolates recovered from an outbreak in an NICU in Ha'il, Saudi Arabia. It is alarming to note the high rate of outbreak isolates with simultaneous production of CTX-M-15 and SHV-12 conferring high-level resistance to oxyimino-cephalosporins.

Effect of Synergistic Action of Bovine Lactoferrin with Antibiotics on Drug Resistant Bacterial Pathogens.

Background and Objectives: The multidrug resistant (MDR) bacterial pathogenic infection is one of the chief worldwide public health threat to humanity. The development of novel antibiotics against MDR Gram negative bacteria has reduced over the last half century. Research is in progress regarding the treatment strategies that could be engaged in combination with antibiotics to extend the duration of these life-saving antibacterial agents. The current study was therefore planned to assess the synergistic effects of bovine lactoferrin (bLF) in combination with different antibiotics that are conventionally used. This synergism would provide a newer therapeutic choice against MDR pathogens. LF is present in mucosal secretions, vastly in milk. LF is considered an important constituent in host defense. In previous reports, LF has been co-administered as a combination antibiotic therapy. Materials and Methods: This study included synergistic (LF + appropriate antibiotic) exposure against 147 locally encountered bacterial pathogens, which were completely characterized strains. The anti-biofilm effects and the outcome of bLF on minimum inhibitory concentrations (MICs) of antibacterials on clinical MDR bacterial pathogens were determined by standard techniques. Results: In our study, synergism of bLF with antibacterial agents were reproducible and found to be significant. LF on its own had an important effect of inhibiting the biofilm production of some significant bacterial pathogens. Conclusion: The results of this study provides useful data on the antibacterial potential of the combination of LF with antibiotics against drug resistant pathogens.

Fecaloma presenting as huge abdominal mass.

Fecal impaction is common in elderly, bed ridden, schizoaffective patients on antipsychotics. Intestinal obstruction due to distal colonic fecaliths is rare as it is amenable to digital manual evacuation and enemas. Our patient presented with abdominal distention, with last bowel evacuation reported 3 months ago. Computed tomography (CT) abdomen demonstrated a huge sigmoid fecalith causing bilateral hydronephrosis. He was managed through laparotomy with sigmoid colon resection and end colostomy.

Impact of Vitamin D Status in Chronic Liver Disease.

BACKGROUND: Vitamin D deficiency is extremely common in chronic liver disease (CLD) patients. Up to 93% of these patients have some degree of vitamin D insufficiency. Liver plays an important role in the metabolism and pleiotropic functions of vitamin D. Vitamin D deficiency has been associated with increased mortality, bacterial infections, portal hypertension complications, and fibrosis severity. We aimed to determine the impact of vitamin D level in CLD. METHODS: One hundred fifty individuals consisting of 75 cirrhotic patients (cases) and 75 respective attendants (controls) were enrolled between July 2015 and July 2017. A detailed clinical and laboratory evaluation was done along with estimation of vitamin D level. Unpaired t-test and analysis of variance was used to compare difference in the level of continuous variables between different groups. Linear regression analysis was performed to analyze the correlation between vitamin D deficiency and severity of liver disease. RESULTS: The age of patients ranged from 18 years to 69 years with mean of 48.85 ± 13.6 years in the case group and 46.57 ± 17.24 years in the control group. Out of 75 CLD patients, vitamin D deficiency (<20 ng/dl) was found in 31 (41.4%) patients, out of which 14(18.7%) suffered from severe vitamin D deficiency (<10 ng/ml). On applying analysis of variance test, there was significant difference in vitamin D level and serum albumin and serum bilirubin (P < 0.05). On linear regression, vitamin D level showed significant negative correlation with Child-Pugh score (r = -0.7379, P < 0.0001) and Model For End-Stage Liver Disease score (r = -0.6671, P < 0.0001). CONCLUSION: Our study concluded that CLD is associated with a significantly low level of vitamin D, which was independent to patient's gender, body mass index, residence, and education level. The findings of our study suggest that awareness of serum vitamin D level in patients with CLD is important. Further studies are required to validate the importance of vitamin D levels and impact of vitamin D supplementation on CLD.

Occult hepatitis B virus infection as a cause of posttransfusion hepatitis in patients with cancers.

BACKGROUND: Prevalence of hepatitis B virus (HBV) infection is increased in patients of cancer with increased mortality. Multiple transfusions of blood and blood-related products are a potential source. AIMS: This study aims to assess the incidence of hepatitis B surface antigen (HBsAg) seroconversion in cancer patients receiving transfusion of blood or blood-related products and identify possible reasons for infection in these patients. MATERIAL AND METHODS: Patients of cancer receiving blood products, who were HBsAg-, anti-hepatitis B core (HBc)-, and HBV DNA-negative prior to transfusion, were tested for HBsAg by ELISA at 6, 12, and 24 weeks after the last transfusion. Blood donors were screened for HBsAg by ELISA. RESULTS: Twenty of 3,600 (0.56 %) blood donors tested positive for HBsAg and were rejected. Nine of 150 (6 %) cancer patients became HBsAg-positive posttransfusion which included seven patients who presented with acute hepatitis B and other two patients who remained HBsAg-positive without hepatitis. In 6/9 (66.6 %) patients, HBsAg positivity was related to blood transfusion as their corresponding blood donors on retesting the stored samples were positive for anti-HBc antibody and HBV DNA. In other three patients, the cause of their HBsAg positivity could not be ascertained. CONCLUSION: Occult HBV infection in blood donors is a potential source of posttransfusion HBV infection in recipients. Anti-HBc antibody and HBV DNA should be tested in blood donors especially when blood is given to cancer patients receiving chemotherapy.

bro {beta}-lactamase and antibiotic resistances in a global cross-sectional study of Moraxella catarrhalis from children and adults.

OBJECTIVES: To compare and contrast the geographic and demographic distribution of bro beta-lactamase and antibiotic MIC(50/90) for 1440 global Moraxella catarrhalis isolates obtained from children and adults between 2001 and 2002. METHODS: One thousand four hundred and forty M. catarrhalis isolates originating from seven world regions were investigated. The isolates were recovered from 411 children <5 years of age and 1029 adults >20 years of age. PCR-restriction fragment length polymorphism (RFLP) was performed to determine bro prevalence and to distinguish between bro types. MIC values of 12 different antibiotics were determined using the CLSI (formerly NCCLS) broth microdilution method. RESULTS: Of the 1440 isolates, 1313 (91%) possessed the bro-1 gene and 64 (4%) possessed the bro-2 gene. Additionally, the prevalence of bro positivity between the child and adult age groups was significantly different (P < 0.0001), though bro-1 and bro-2 prevalences within age groups were not significantly different. Consistently higher beta-lactam MICs were observed for M. catarrhalis isolates originating in the Far East. Significant correlations in MICs were observed for several antibiotic combinations, including all five beta-lactams with each other, and among the two quinolones. CONCLUSIONS: The worldwide prevalence of bro gene carriage in clinical isolates of M. catarrhalis is now approaching 95%, with children significantly more likely to harbour bro-positive isolates than adults. Further, statistically significant differences in the distribution of beta-lactam MICs were observed between different world regions, particularly with respect to the Far East.

Knowledge and perceptions of diabetes in a semi-urban Omani population.

BACKGROUND: Diabetes mellitus is a major public health problem in the Sultanate of Oman. This study aimed to evaluate the knowledge and perception of diabetes in a sample of the Omani general population, and the associations between the elements of knowledge and perception, and socio-demographic factors. METHODS: The study was carried out in two semi-urban localities. A total of 563 adult residents were interviewed, using a questionnaire specifically designed for the present study. In addition to demographic information, the questionnaire contained questions on knowledge related to diabetes definition, symptoms, risk factors, complications and preventative measures, as well as risk perception for diabetes. RESULTS: Knowledge of diabetes was suboptimal. The percentages of correct responses to questions on diabetes definition, classical symptoms, and complications were 46.5%, 57.0%, and 55.1%, respectively. Only 29.5%, 20.8% and 16.9% identified obesity, physical inactivity and a positive family history, respectively, as risk factors for diabetes. A higher level of education, a higher household income, and the presence of a family history of diabetes were found to be positively associated with more knowledge. CONCLUSION: This study demonstrated that there is lack of awareness of major risk factors for diabetes mellitus. Level of education is the most significant predictor of knowledge regarding risk factors, complications and the prevention of diabetes. Given that the prevalence of diabetes has increased drastically in Oman over the last decade, health promotion seems essential, along with other means to prevent and control this emerging health problem.

Analysis of VanA vancomycin-resistant Enterococcus faecium isolates from Saudi Arabian hospitals reveals the presence of clonal cluster 17 and two new Tn1546 lineage types.

OBJECTIVES: The aim of this study was to characterize 34 vancomycin-resistant VanA Enterococcus faecium isolates obtained from two hospitals in Saudi Arabia and to assess Tn1546 variation within these isolates. METHODS: PFGE and multilocus sequence typing (MLST) genotypes, antibiotic susceptibility patterns, the presence of enterococcal surface protein (esp) and hyaluronidase (hyl) genes and conjugation frequencies were determined. In addition, Tn1546 elements were characterized. RESULTS: PFGE and MLST analysis revealed the presence of 31 and 6 different genotypes, respectively. Further, three new ST types were discovered. Ninety-seven percent (33/34) of the isolates were associated with clonal complex 17 (CC17), with all isolates but one being resistant to ampicillin and all isolates being susceptible to linezolid. The esp and hyl genes were found in 44% (15/34) and 53% (18/34) of the isolates, respectively. Tn1546 analysis revealed that the isolates belonged to five different groups, including two new lineages. The IS-element insertions described did not abolish the transfer of VanA resistance. CONCLUSIONS: VanA vancomycin-resistant E. faecium isolates obtained from Saudi Arabian hospitals include CC17 MLST types, a clonal cluster associated with E. faecium nosocomial infection worldwide. Novel E. faecium MLST types are circulating in Saudi Arabia, as well as novel Tn1546 types. It seems likely that CC17 E. faecium isolates may be distributed throughout the Middle East as well as Europe, America, Africa and Australia.

Effect of bending exercise on gastroesophageal reflux in symptomatic patients.

BACKGROUND: Recumbency and bending are thought to provoke symptoms of reflux in patients with gastroesophageal reflux disease (GERD). The effect of exercise which involved bending and abdominal contractions was evaluated in symptomatic patients of GERD using continuous 24-hour ambulatory esophageal pH test. METHODS: Twenty-five patients with GERD, confirmed by abnormal 24-hour esophageal pH study, performed exercise for 30 minutes consisting of 5 sessions of 6 minutes each. The exercise involved toe touching from supine, sitting and standing position of 2 minutes' duration each. Each 2 minutes' period included 8 repetitions of the same exercise of 15 seconds' duration. 24-hour esophageal pHmetry was done on day 1 without exercise and on day 2 with 30-minute exercise. Reflux time percent (RT%) pH <4 was compared between days 1 and 2 and 30 minutes before and during exercise. RESULTS: Fourteen patients were upright refluxers and 11 patients were combined refluxers, which included 4 patients with supine reflux and 7 patients who refluxed both in supine and upright positions. The median (range) 24-hour RT% on day 1 and day 2 was 7 (5-40) and 7 (4-46), respectively (p=0.15). RT% during 30 minutes exercise compared with 30 minutes before exercise was 6.6 (0-60) and 0.0 (0.0-80) (p=0.02), respectively. In combined and upright refluxers, RT% during and before exercise was 13 (0-53) and 0.0 (0.0-42) (p=0.008), respectively and 0.0 (0-60) and 0.0 (0-80), (p=0.71), respectively. RT% between upright and combined refluxers during exercise was 0.0 (0-60) and 13 (0-53), respectively (p=0.004). The mean (SD) LES pressure in mmHg in combined and upright refluxers was 7 (2.9) and 19.6 (6.8), respectively (p=0.008). Esophagitis in combined and upright refluxers was seen in 8 patients (72.7%) and 2 patients (14.3%), respectively. Two patients (8%) developed symptoms during exercise. CONCLUSION: Exercise which involves bending precipitates reflux in patients with moderate-to-severe GERD.

Perioperative complications of intraocular lens exchange in patients with opacified Aqua-Sense lenses.

PURPOSE: To evaluate the perioperative complications of intraocular lens (IOL) exchange in 25 eyes of 22 patients with opacified Aqua-Sense IOLs (Ophthalmic Innovations International). SETTING: Department of Ophthalmology, University Hospital Aintree, Liverpool, United Kingdom. METHODS: The study comprised 22 patients (25 eyes) who had previous phacoemulsification and implantation of Aqua-Sense single-piece hydrophilic acrylic IOLs in the capsular bag and developed severe late opacification of the IOL. All patients reported glare and deterioration in vision. The IOLs were explanted and replaced with new lenses. The perioperative complications were evaluated. The best corrected visual acuity (BCVA) before and after surgery was compared. RESULTS: In 24 eyes, the opacification was complete, involving the optic, haptics, and substance of the IOLs. Uneventful IOL exchange and placement of a new IOL in the bag was achieved in 13 eyes (52%). Complications occurred in the remaining 12 eyes (48%). Ten eyes (40%) developed zonular dehiscence, 4 (16%) of which were managed with anterior chamber IOL implantation. One eye (4%) developed posterior capsule rupture and 1 eye (4%), posterior capsule rupture and zonular dehiscence. The cornea decompensated in 2 eyes (8%). One eye (4%) developed Pseudomonas keratitis. The mean BCVA (decimal scale) before and after IOL exchange was 0.57 +/- 0.24 and 0.60 +/- 0.28, respectively. There was no significant difference in visual acuity between before and after IOL exchange (P=.782, paired t test). CONCLUSIONS: Explantation of Aqua-Sense IOLs was challenging because of the tight adherence of the optic and haptics to the capsule. Long-term follow-up of patients with Aqua-Sense IOLs should be maintained.

Lysine fortification of wheat flour improves selected indices of the nutritional status of predominantly cereal-eating families in Pakistan.

Wheat provides more than 50% of the protein and calorie intake of the population of Pakistan. Legumes and animal protein that could complement the amino acid pattern of wheat, in which lysine is the first limiting amino acid for utilization of protein, are not affordable by members of lower socioeconomic groups in developing countries. The purpose of the study was to determine whether lysine fortification of wheat flour would have a positive impact on populations consuming a predominantly wheat-based diet. A double-blind study was carried out for three months on the outskirts of Peshawar, Pakistan. Forty families received wheat flour fortified with lysine, and 40 families received wheat flour without lysine. Wheat provided 59% of the protein for men, 65% for women, and 58% for children. The weight and height of the children in both groups increased during the study, but the increase was significantly greater in the lysine group. Hemoglobin increased significantly in the women receiving lysine-fortified flour. Transferrin levels increased significantly in men, women, and children in the lysine group as compared with those in the control group. Prealbumin increased significantly in adults receiving additional lysine but decreased in children. Men, women, and children in the lysine-supplemented families had significant increases in CD4, CD8, and complement C3 as compared with controls. These results indicate that lysine fortification of wheat flour can significantly improve sensitive indicators of nutritional status in a population consuming a diet in which 58% to 65% of the protein, depending on age and sex, is supplied by wheat.

Longitudinal growth patterns of Pakistani infants in a clinic based growth promotion program.

OBJECTIVE: To describe the operation of growth monitoring and promotion (GMP) clinic and longitudinal growth patterns of children. DESIGN: Prospective observation and intervention. SETTING: Outpatient department of a teaching hospital. METHODS: Less than 6 months old infants were registered at GMP clinic and followed for up to two years of age. Mothers were provided information, education and counselling about healthy growth of their infants. The outcome measure was change in weight after follow-up. RESULTS: We enrolled a cohort of 553 children in the first 6 months of life, of which 318 were males. Mean follow up period was 15.7 (SD+/-6.4) months. At enrollment 207 were underweight [weight-for-age Z score (WAZ<-2], of which 153 were from low-income families. The children from poorer families also gained weight regularly, although it was less than the higher income families. Of 346 infants with normal weight at registration, 305 maintained their weight gain by last follow-up visit. Of 207 underweight infants at enrollment 128 improved their weight gain by the last follow-up visit. Overall 433 infants followed-up at our GMP clinic either maintained or improved their weight gain. CONCLUSIONS: Children at risk of undernutrition should be identified at an early age and through effective interaction between health workers and the family, their growth can be improved. Children of poor families can also benefit from this activity, provided a comprehensive approach is made available.

Prevalence and clinical characteristics of headache in a rural community in Oman.

OBJECTIVES: To perform a prospective epidemiological study of headache in a rural community in Oman, assessing prevalence, symptom profile, and health care utilization pattern. METHODS: Using a door-to-door survey prevalence estimates were based on a detailed structured headache assessment questionnaire performed in 1158 subjects. Migraine and tension-type headache were diagnosed according to the International Headache Society criteria. RESULTS: The crude lifetime and last-year prevalence of headache were 83.6% and 78.8%, respectively, with a female preponderance. The last-year prevalence of migraine and tension headache was 10.1% and 11.2%, respectively. There was no significant gender difference in migraine prevalence (4.5% in male and 5.6% in female), but tension-type headache was 2.6 times more common in females (3.1% in male and 8.1% in female). Last-year prevalence of frequent headaches was 5.4%. Forty eight percent of respondents sought medical assistance for their headaches and 79% were using medication, 40% of them used self-medication. CONCLUSIONS: This prospective study shows that headache is also highly prevalent in this community. Migraine and tension-type headache have the same prevalence, but the sex distribution for migraine is different from that observed in the Western world. Tension-type headache prevalence was substantially lower than that observed in other parts of the world. Frequent headaches were as common as in other population-based studies worldwide. Analgesic use/overuse probably also coexisted with headache, because self-medication was quite common.

In vitro Inhibition of HHV-6 replication by sophocarpines.

The virostatic activity of sophocarpines and gancyclovir (GCV) was tested using HHV-6 Z29 strain and Molt-3 cells. The cytotoxic (IC(50)) and the antiviral (ED(50)) values were first experimentally determined and selective indices (SI) were then calculated. The SI values for sophocarpines 1 and 2 and GCV were in the order 184, 183, and 23, respectively. Though preliminary, these findings indicate that sophocarpines have the potential to inhibit HHV-6 replication.
