48 Background: More than 80% of patients with hematologic malignancies and 10-50% of patients with solid tumors are expected to experience fever after one cycle of chemotherapy. Studies have shown all-cause mortality to be 15% higher in cancer patients with febrile neutropenia than comparably matched patients without febrile neutropenia and compliance for choice of empiric antibiotics in febrile neutropenia to be as low as 56%. Methods: We conducted a retrospective chart review of patients who presented with febrile neutropenia to our institution for one year prior to and after implementation of a CPOE set. Data was collected on basic demographics, oncological diagnosis, labs, choice of antibiotics and dosing frequency. Awareness sessions were conducted among admitting staff following the initial retrospective analysis followed by implementation of a CPOE set in order to improve guideline concordant management of febrile neutropenia patients. The IDSA risk was assessed based on the above data and the pre and post order set compliance with IDSA guidelines were compared. Fisher’s exact test was applied to assess the percentage of compliance before and after implementation of the order set, with significance set at two-sided p value < 0.05. Results: Among the patients managed before order set, 15 of the total 26 (58%) were found to be non compliant with IDSA guidelines in terms of either antibiotic choice or dosing frequency. A post order set analysis showed that only 7/27 (26%) were non compliant with IDSA guidelines. The Fisher exact test showed a statistically significant value of 0.0267 (p < 0.05). Conclusions: Education and implementation of a CPOE order set showed significant improvement in compliance with IDSA guidelines for management of febrile neutropenia. Based on the data from our study an IDSA concurrent institutional guideline for management of febrile neutropenia was formulated and further efforts are under way to incorporate results in our new EMR order set entries.[Table: see text]

ABSTRACT Introduction To compare pain medication refill rates for adult septoplasty and rhinoplasty patients before and after initiating a multimodal analgesic protocol for reducing opioid prescriptions (PROP). Materials and Methods Data from 58 adult patients were retrieved by retrospective chart review (19 septoplasties and 10 rhinoplasties before initiating PROP in September 2018 and 21 septoplasties and 8 rhinoplasties after PROP). We selected consecutive septoplasties and rhinoplasties, at which time a new discharge order set was implemented. The new order set consisted of 10 oxycodone tabs (5 mg), 100 acetaminophen tabs (325 mg), and 28 celecoxib tabs (200 mg). The primary outcome variable was the number of initial opioid prescriptions and refills filled by any provider. Results Among the septoplasties, there was a 46% decrease in total morphine milligram equivalent (MME) prescribed, from a mean of 202.0 mg in the non-PROP group (95% CI, 235.4, 174.6) to 108.6 mg in the PROP group (95% CI, 135.8, 81.4), with no difference in refill rates. Among the rhinoplasties, there was a 51% decrease in total MME prescribed, from a mean of 258.8 mg in the non-PROP group (95% CI, 333.4, 184.1) to 126.6 mg in the PROP group (95% CI, 168.1, 85.0) with no difference in refill rates. Conclusions The outcomes after PROP implementation for septoplasty and rhinoplasty at our institution suggest that opioid prescription rates can be significantly decreased to manage postoperative pain, with no difference in opioid refill rates. The results also warrant further investigation into patient pain, satisfaction, provider efficiency, and healthcare costs.

Polymorphisms in genes that control immune function and regulation may influence susceptibility to pulmonary tuberculosis (TB). In this study, 14 polymorphisms in 12 key genes involved in the immune response ( VDR, MR1, TLR1, TLR2, TLR10, SLC11A1, IL1B, IL10, IFNG, TNF, IRAK1, and FOXP3) were tested for their association with pulmonary TB in 271 patients with TB and 251 community-matched controls from the Republic of Moldova. In addition, gene–gene interactions involved in TB susceptibility were analyzed for a total of 43 genetic loci. Single nucleotide polymorphism (SNP) analysis revealed a nominal association between TNF rs1800629 and pulmonary TB (Fisher exact test P = 0.01843). In the pairwise interaction analysis, the combination of the genotypes TLR6 rs5743810 GA and TLR10 rs11096957 GT was significantly associated with an increased genetic risk of pulmonary TB (OR = 2.48, 95% CI = 1.62–3.85; Fisher exact test P value = 1.5 × 10−5, significant after Bonferroni correction). In conclusion, the TLR6 rs5743810 and TLR10 rs11096957 two-locus interaction confers a significantly higher risk for pulmonary TB; due to its high frequency in the population, this SNP combination may serve as a novel biomarker for predicting TB susceptibility.

Wasting on children is an important public health problem because of its considerable impact on their health and growth. This problem could lead to iron deficiency which could induce infection disease and probably lower a child’s intelligence as a long-term effect. This study aimed to analyze factors related to wasting on 12-59 months children in Bulili Public Health Center (PHC), Palu City. The analytical descriptive study designed with a cross-sectional approach was applied in this study. One hundred and twenty-one subject was selected from 283 children with purposive sampling technique. Data were analyzed with chi-square and Fisher exact test with significant (p < 0,05). The result showed that most children with low birth weight experienced wasting with a p-value = 0,000. Most of the children from higher-income families did not experience wasting with a p-value = 0,004. Most children who didn’t receive breastfeeding milk did not experience wasting with a p-value = 0,958. This study concluded a correlation between low birth weight and income to wasting, but breastfeeding practice was not related.

Introduction: Seasonal hyper-acute panuveitis (SHAPU) is a sight-threatening disease and its management is challenging. Objective: To study the profile and evaluate the visual outcome of the patients of clinicallydiagnosed cases of SHAPU after treatment. Subjects and methods: A retrospective interventional hospital-based study was carried out involving 21 subjects with clinically-diagnosed SHAPU. The data were retrieved from the record section of the hospital and analyzed. The variables studied were demographic pattern, clinical condition, duration of presentation and visual acuity before and after the treatment. Statistics: The data were analyzed using Epi Info version 2000. Percentage prevalence, mean values with standard deviation, relative risk, 95% CI and p value were calculated. P value of < 0.05 was considered to be significant. Results: Among the 21 cases, the numbers of male and female were 11 (52.4 %) and 10 (46.7 %) respectively. A comparative analysis of gender in children and adults did not show any significant difference (RR=0.47, 95% CI = 0.22 - 1.01, Fisher exact test: p = 0.14). The mean for all ages was 7 ± 12.68 years, while the mean age in pediatric cases was 4.5 ± 3.91 years. Thirteen (61.9%) cases occurred in children below fifteen years. Fifteen (71.4 %) cases reported during September and October. Presenting visual acuity of all cases was less than 3/60. All of them received medical treatment. By the end of the 4th week, seven (33.3 %) patients regained vision to 6/18. Conclusion: SHAPU is more prevalent in pediatric age group. It is equally prevalent among males and females. The visual acuity can improve with early medical treatment. Keywords: SHAPU; panuveitis; steroid; phthisis bulbi DOI: 10.3126/nepjoph.v2i1.3702 Nep J Oph 2010;2(1) 35-38

Snake bites are a rare but challenging problem for surgeons. The purpose of our study was to evaluate our experience with snake bites at a regional medical center. We reviewed patients treated for snake bites from 2004 to July 2008. Demographics, clinical information, and outcomes were documented. Descriptive statistics were used, and χ2, t test, and Fisher exact test were used to compare patients based on antivenin use. A P value < 0.05 was considered significant. Over the study period, 126 patients presented to the emergency department with 44 (35%) requiring hospital admission. The average age was 38 years (range, 2 to 76 years); 66 per cent were male and 95 per cent white. Bites most commonly occurred in the summer and fall months with none from December through March. Copperhead bites accounted for 50 per cent of bites. An average of 4.8 vials of antivenin was given to 61 per cent of admitted patients with 93 per cent receiving the drug within 6 hours. Minor reactions to antivenin occurred in three patients (11%). Two patients required surgery (5%), and the readmission rate was 7 per cent. There was no known morbidity or mortality. When comparing patients who received antivenin with patients who did not, the only significant clinical variables were an increased prothrombin time (12.1 vs 11.7, respectively; P = 0.048) and a longer length of hospital stay (3 vs 1.8 days, P = 0.0006) in patients receiving antivenin. The majority of patients with snake bites can be treated with supportive care and antivenin when indicated. Antivenin use at our institution is largely based on physical findings and not related to laboratory values.

Background: Otoscopic procedure like tympanoplasty is one of the magic wands that an ear nose throat surgeon possesses to alleviate the suffering of a hearing impaired patient. Endoscopic trans-tympanic pop in technique is an alternative method where tympanic fascial graft is placed medial to tympanic membrane remnant through the perforation without elevation of tympanomeatal flap and angled endoscope is used to assess the ossicular chain.Objective: The study was done to compare the results of endoscope assisted trans-tympanic pop-in tympanoplasty with permeatal underlay tympanoplasty.Methods: The study is a prospective, longitudinal and experimental study conducted in Kathmandu Medical College Teaching Hospital from January 2016 to June 2016. A total of sixty-two patients, thirty-one in study and thirty-one in control group were present. The comparison was made in terms of success rate, decrease in taste sensation and time taken for the procedure. Data analysis was done by SPSS version 20. Categorical data were tested by Fisher Exact test and p-value of <0.005 was considered statistically significant.Result: Among 62 patients, 55 had successful graft uptake (88.7% success rate). Hearing improvement was seen in 51 patients (88.25%). Regarding taste sensation 5 out of 62 had decrease in taste sensation after surgery (8%). Time taken was approximately 30 to 45 minutes (mean =44.1min) in endoscopic transtympanic pop-in type and 60 to 90 minutes (mean =73.8 min) in permeatal underlay type.Conclusion: We can conclude that endoscopic trans-tympanic pop-in tympanoplasty gives similar hearing and graft uptake result but with less time and greater ease as compared to permeatal underlay technique.

e18139 Background: KRAS mutations are the most common driver mutation indentified in NSCLC, occurring in 20 - 30% of adenocarcinomas. While several studies suggest KRAS predicts for lack of response to TKI therapy, few data exist regarding its association with outcomes for patients treated with cytotoxic chemotherapy. This study explores the association between KRAS mutations and outcomes (RR, PFS) in a cohort of patients treated with frontline platinum/pemetrexed (PPm) based therapy. Methods: In this retrospective chart review, we evaluated RR and PFS for 16 KRAS + EGFR – pts treated with carboplatin (AUC 5-6) or Cisplatin 75mg/m2 and (Pm)pemetrexed (500 mg/m2) +/- (B)bevacizumab 15mg/kg. For comparators, we identified 19 KRAS - EGFR - patients treated with the same regimen. Maintenance therapy with Pm or Pm+B was given at the discretion of the treating physician. KRAS and EGFR mutational status were assessed by RT-PCR on tumor tissue collected at first diagnosis. RR was assessed using RECIST criteria. Kaplan-Meier estimates for PFS were evaluating using log rank test. Fisher exact test was used to assess the association between KRAS mutation status and response rate. Results: The groups were similar in age (KRAS + mean 61 vs. 60; p=0.87), gender (62% vs. 57% F; p= 0.9), ECOG 2 (0 vs. 10%,p=0.47), smoking hx (93% vs. 94% current/former smokers, p=0.7), brain mets (0% vs. 18% p=0.22), mean number induction cycles (4 in each, p=0.6), cisplatin and bevacizumab use (12% vs 10%, p > 0.1;10% vs. 40%, p=0.10). Pm maintenance was used in 31% KRAS+ (5/16) and 26% KRAS-(5/19) (p=0.79). P+B maintenance was used in 12% (2/16) and 5% (1/19) (p=0.70). RR was 56% in the KRAS + (9/16) vs. 36% KRAS- (7/19) respectively (p=0.3). There was a statistically significant improvement in PFS in the KRAS + group (10.3 mos vs. 5.7 mos, p =0.03). Conclusions: In this small retrospective review, KRAS mutations appeared to be associated with a non-significant improvement in RR and significant improvement in PFS for patients treated with frontline PPm based therapy. Future prospective studies should investigate and validate the predictive value of KRAS for this cytotoxic regimen. [Table: see text]
