The purinergic P2Y12 receptor regulates microglial activation, resulting in persistence and aggravation of pain in neuropathic and nociceptive pain models. We conducted a retrospective chart review to explore the analgesic potency of the P2Y12 receptor-specific antagonist, clopidogrel, for clinical management of postoperative pain in patients who underwent abdominal surgery. Twenty-seven patients with cardiovascular comorbidities, who underwent laparoscopic abdominal surgery and had ceased aspirin (ASP, n = 17) or clopidogrel (CLP, n = 10) for 14 days pre-operatively, were enrolled retrospectively. In both groups, the number of opioids and non-steroidal anti-inflammatory drugs (NSAIDs) consumed for managing postoperative pain was compared using the chi-square test and Mann–Whitney test. Our results showed that from postoperative day (POD) 0 to POD 3, the average numerical rating reflecting the postoperative pain was comparable between the two groups (CLP: 4.0 ± 1.4 vs. ASP: 3.7 ± 0.8, P-value = 0.56). However, at POD 7, opioid consumption in the CLP-treated group (fentanyl-equivalent dose: 0.49 ± 0.56 mg) was significantly lower than that in the ASP-treated group (1.48 ± 1.35 mg, P-value = 0.037). After reaching a stable state by repeated systemic administration, clopidogrel sustained the analgesic efficacy for a certain period. In conclusion, microglial P2Y12 receptors may mediate signal transduction of postoperative nociceptive pain and enhance clinical opioid analgesia.

Abstract Introduction Prolonged opioid usage remains a concern in pain management in procedural care. Recent evidence also suggests that a considerable number of patients who were prescribed opioids struggle with transitioning to non-opioid pain medications. As a continuous effort to reduce opioid consumption following burn surgical procedures, our institution recently evaluated methadone administration for burn procedural care in patients with 20–30% total burn surface area (TBSA) requiring excision and grafting. Methods After IRB approval, we performed a retrospective chart review of patients who underwent excision and grafting procedure for 20–30% TBSA burn injuries between January 1, 2019 and June 30, 2020. The following data was evaluated: postoperative opioid consumption, postoperative pain intensity (rated as “No Pain” [NRS=0], “Minor Pain” [NRS 1 to 3], “Moderate Pain” [NRS 4 to 6], “Severe Pain” [NRS 7 to 10]), time to physical therapy and time to hospital discharge. Data was analyzed using chi square/Fisher exact test for categorical variables and t-test/Wilcoxon rank sum test for continuous variables. Results Our preliminary data included 12 patients who met inclusion criteria, of which two patients received methadone administration. Our patient sample consisted of average age of 43 years, 75% male, and 24% TBSA (92% were flame burns). Patients in both methadone and non-methadone groups had no significant differences in medical histories and TBSA (23% TBSA in methadone, 25% TBSA in non-methadone). There was no significant difference in reported preoperative pain intensity between the two groups, rating moderate to severe. Postoperative pain intensity remained the same, rating moderate to severe and controlled with fentanyl, oxycodone, morphine and non-opioid analgesics. While there was no difference in postoperative fentanyl, opioid and non-opioid analgesic consumptions between the two groups, morphine consumption was significantly lower in the methadone group compared to non-methadone group (2±2 mg vs 51±54 mg, respectively, p=0.02). There was no significant difference between average time from surgery to first physical therapy session and time to hospital discharge (about 21 days after surgery) between the two groups. Conclusions This evaluation shows a potential trend in reduction of inpatient postoperative opioid consumption with the conjunctive administration of methadone, although a bigger sample size is needed for further assessment.

Background: Fear of poor wound healing have curtailed the use of diathermy for making skin incision. Scalpel produces little damage to surrounding tissue but causing more blood loss. Our aim of study was to compare electrocautery incision with scalpel incision in terms of incision time, blood loss, postoperative pain and wound infection.Methods: Total of 104 patients were included in the study undergoing midline abdominal surgery. Patients were randomized into electrocautery (group A) and scalpel (group B). The incision dimension, incision time and blood loss were noted intraoperatively. Postoperative pain was noted on postoperative day 2 using visual analog scale. Wound complications were recorded on every postoperative day till the patient was discharged.Results: 52 patients in each of the two groups were analyzed. There was significant difference found between group A and group B in terms of mean incision time per unit wound area, 8.16±1.59 s\cm2 and 11.02±1.72 s\cm2 respectively (p value=0.0001). The mean blood loss per unit wound area was found to be significantly lower in group A (0.31±0.04 ml\cm2) as compared to group B (1.21±0.21), p value=0.0001. There was no significant difference noted in terms of postoperative pain and wound infection between both groups.Conclusions: Electrocautery can be considered safe in making skin incision in midline laparotomy compared to scalpel incision with comparable postoperative pain and wound infection with less intraoperative blood loss and less time consuming.

Abstract Objective Spina bifida primarily affects people of low and middle socioeconomic status. Herein, we describe the outcome of myelomeningocele surgical management in Iran and predictors of its postoperative complications and mortality. Methods This retrospective chart review studies the children who underwent surgical management for myelomeningocele in Shiraz, Fars province, Iran, from May 2001 to September 2020. To this end, we investigated mortality and 30-day complications and the factors that determined the operation's outcome. Results 256 patients were enrolled. The median age at the operation was roughly eight days (IQR: 7). The most common site of involvement of Myelomeningocele (MMC) was Lumbosacral (86%, n = 204). At the evaluation conducted prior to operation, CSF leaking was observed in 7% (n=16) of the patients. Postoperatively, 5.7% of the patients were expired in the 30 days following the operation (n = 14), while 24% needed readmission (n = 47). The most common complications leading to readmission included wound dehiscence (n = 10, 42%) and wound purulence (n = 6, 25%). No variable was significantly associated with postoperative complication except for the site of the lesion (p-value = 0.035) and the presence of the lipid content in the defect (p-value = 0.044). Conclusions Most patients born with MMC are referred for the neurosurgical evaluation following their birth; however, as results show there is much left to be desired compared with the 48h recommended by The Congress of Neurological Surgeons. Here, we concluded that presence of lipid compartment in the lesion and the site of the lesion are the two factor that were associated with the rate of mortality. However, further investigation into preoperative interventions and risk factors to mitigate risk of postoperational complications and mortality is highly encouraged. We highly advocate for the investigation and dissemination of the outcome of the conventional surgical management of MMC in financially restrained areas; because they can show the limitation these settings are confronted with (that are in a way unique to them and different from the resourceful settings) and provide a model for other similar areas with limited suitable care.

Objective: To determine the safety of ibuprofen used for postoperative pain control following palatoplasty in pediatric patients. Design: Retrospective chart review. Setting: Tertiary care, pediatric hospital. Participants: Patients who received ibuprofen for postoperative pain control after palatoplasty. Main Outcome Measures: Number of doses of ibuprofen given during hospitalization and the presence of postoperative primary or secondary bleeding following palatoplasty. Detection of postoperative hemorrhage was obtained from (1) chart review from inpatient hospitalization after palatoplasty, (2) chart review of each patient’s 3-week postoperative clinic visit, and (3) phone call to caretakers from primary author. Results: Thirty-two patients underwent palatoplasty who received ibuprofen for control of postoperative pain. Mean number of inpatient doses given was 4.8 (range: 1-17). None (0%) experienced hemorrhage in the hospital before discharge. Thirty-two (100%) patients were seen at a 3-week follow-up and no (0%) episodes of postoperative hemorrhage were noted. Seventeen (53%) caretakers of patients responded to contact by phone and confirmed no subsequent bleeding. Conclusions: Ibuprofen may not increase postoperative hemorrhage after palatoplasty. Further studies will be needed to evaluate safety on a larger scale.

Objectives: The objective of this study was to assess the utility of novel macular hole indices of Optical Coherence Tomography (OCT) and predicting the functional outcome of surgery. Methods: This was a retrospective chart review of 28 eyes who underwent surgery for idiopathic Full Thickness Macular Hole (FTMH) at The Aga Khan University Hospital (AKUH), Karachi from January 2016 to March 2020. Data of preoperative OCTs were recovered from data server of OCT machine. Measurements of the pre-operative OCTs were calculated using caliper function of OCT software by two independent technicians. Parameters included Macular Hole Index (MHI), Traction Hole Index (THI), Hole Form Factor (HFF) and Diameter Hole Index (DHI) were recorded. Receiver operating characteristic (ROC) curve was used to evaluate the performance of DHI, THI, HFF and MHI for improved BCVA after surgery, by looking at sensitivity, specificity and area under curve (AUC). P-value of <0.05 was considered significant. Results: Out of 30 eyes, final data analysis was done for 28 eyes. Mean age was 61.5 ± 6.2 years. Mean pre-operative and 6 months post-operative LogMAR best corrected visual acuity (BCVA) was 0.84 ± 0.23 and 0.32 ± 0.30 (p-value <0.001). Area under the curve with 95% confidence interval estimated for DHI, THI, HFF, and MHI was [0.750 (0.559 to 0.889)], [0.827 (0.637 to 0.943)], [0.846 (0.660 to 0.954)], [0.827 (0.637 to 0.943)]. Cut off values for predicting good functional outcome (post-op BCVA equal or better that 0.4) for DHI, THI, HFF and MHI were 0.454, 1.086, 0.856 and 0.501 respectively. All ROC value of less than 0.5 were considered unlikely to predict functional outcomes with macular hole indices. Conclusion: Novel macular hole indices can be used as a tool to predict the functional outcomes of macular hole surgery. Larger studies may be required to assess their wider effectiveness. doi: https://doi.org/10.12669/pjms.37.5.4126 How to cite this:Tayyab H, Siddiqui R, Jahangir S, Hashmi S.

Abstract Abstract 4892 Introduction In multiple myeloma (MM), hemoglobin (Hb) levels have long been part of staging of the disease and an important determinant in assessing treatment options, response to therapy and prognosis. The causes of a low Hb level are complex, but reflect in part the extent of myeloma cell infiltration in the bone marrow. Changes in the level of the monoclonal immunoglobulin protein in the blood and/or urine (M protein) serve as the main surrogate marker for response to treatment and progression of disease in the majority of patients (pts). This analysis explores the longitudinal relationship between treatment response (using M protein levels from serum protein electrophoresis [SPEP] results) and Hb levels. Methods This retrospective chart review included all pts who initiated drug treatment for relapsed/refractory MM between Jan-06 and Dec-07, inclusive, at Princess Margaret Hospital, Toronto, ON. Hb and M protein (SPEP) results were collected before the start of each treatment cycle. These results were then plotted over time to explore the association between these 2 variables. Results 136 of 281 (48.4%) of pts treated for relapsed/refractory MM had at least one simultaneous measurement of Hb and serum M protein levels and were included in the analysis. Mean age was 66 (SD±9.7) years, 65% of pts were male. More than half (63.2%) of the pts were receiving treatment for 1st MM relapse. Treatments for relapsed/refractory MM included cyclophosphamide ± steroids (33.1%), bortezomib-based regimens (20.6%), thalidomide-based regimens (26.5%), steroid monotherapy (15.4%), and other regimens (4.4 %). Patients received between 1 and 17 cycles of therapy (mean = 2.5 ± 2.9 cycles). Supportive care measures included erythropoiesis stimulating agents (ESAs) in 33.8% [mean dose was 488 (SD±23) μg q3 weeks and 42,343 (SD±7,768) IU weekly for darbepoetin alfa and Epoetin alfa, respectively], RBC and/or platelet transfusions in 17% (14.1% RBC and 6.7% platelets), and G-CSF in 7.4% of pts. The plot below (Figure 1) demonstrates a decrease in serum M protein levels over time and an inverse relationship between Hb and serum M protein levels. Both the decrease of serum M protein levels (p-value <0.001)) and the relationship to rising Hb levels (p-value < 0.001) were found to be statistically significant based on mixed model analyses (linear model taking into account repeated measurements) after accounting for confounding factors such as transfusions and ESA use. Conclusion There was a statistically significant improvement in disease burden across all treatments as evidenced by the drop in serum M protein levels over the cycles of therapy, which was accompanied by a decrease in the level of anemia. A statistically significant inverse relationship between Hb and serum M protein levels was observed in this exploratory analysis. Further studies are required to assess the relevance of Hb change as a viable clinical surrogate marker of response in MM and its potential predictive impact on outcome over time.

e19508 Background: Multiple myeloma (MM) diagnostic costs, including bone marrow (BM) studies: (flow (F), aspirate (manual differential) (A) and biopsy (Bx)) are increasing. BM studies already have underlying discordance issues that may lead to repetitive studies. Thus, elucidation of characteristics associated with concordant/discordant BM studies in identifying plasma cell percentage (PC%) of ≥10, a key MM diagnostic criteria, arises. Methods: A retrospective chart review (total of152 patients diagnosed with MM and managed at UTMB through 1/2016-1/2018) was completed. 56 subjects met inclusion, PC ≥10% in any BM study, and exclusion criteria. Subjects were grouped into BMA vs BMBx and BMF vs BMBx groups and subdivided into MM subtypes for exploratory review. Two-sample Independent t-test (CI 95%) and descriptive statistics were used for comparison of variables. Two-sided p value ≤ 0.05 was considered significant. Results: Sensitivities in identifying BM PC≥10% were as follows: BMA (66.1%), BMF (39.3%) and BMBx (96.4%) (Gold standard: BMA+BMF+BMBx (100%)). Concordance rates were at 60.7% between BMA and BMBx and 35.7% between BMF and BMBx. Larger BMBx spicule size (mean(cm) = 1.3(1.1-1.48) x 0.27(0.22- 0.31) x 0.21(0.19-0.22), p = 0.037) and higher B2 microglobulin (B2m) levels (mean(mcg/mL) = 11.92 (8.04- 15.79), p = 0.003) were associated with BMA and BMBx concordance in typical/secretory MM types but not in oligo-secretory and non-secretory subtypes of MM, nor is associated with BMF and BMB concordance or discordance. Meanwhile, # of BM acquisition attempts, tool types (hand trochar vs drill) for BM acquisition, LDH and CRP levels had no significant associations with concordance or discordance in any BM study groups. Conclusions: BMF is the least sensitive in identifying PC≥10% likely due to PC damage during flow cytometry, and it may be prudent to just perform BMA with BMBx to save on costs. The associations between larger spicule sizes and higher B2m levels to BMA and BMBx concordance are likely due to an increase in the chance of identifying monoclonal PCs in bigger samples, and greater monoclonal PC tumor burden, respectively, and may have predictability benefits.

AbstractPurpose:To determine whether the combination of bupropion SR and varenicline offers improved smoking cessation outcomes compared to varenicline monotherapy or to combination of bupro-pion SR and nicotine patch.Methods:This retrospective chart review included 489 volunteer enrolees in a Veterans Affairs (VA) tobacco cessation clinic who received one of the three treatments upon clinic enrolment. The study endpoints were smoking cessation and clinic completion rates, changes in the number of cigarettes smoked, carbon monoxide (CO) levels, urges to smoke, self-confidence to quit and medication-attributed adverse effects.Results:The relative smoking cessation rates were 33%, 32%, and 40% for bupropion SR and nicotine patch, bupropion SR and varenicline, and varenicline groups, respectively. The 0.21 p value established that no significant cessation rate differences existed between any of the groups. Varenicline alone or in combination was as well tolerated as the combination of bupropion SR and nicotine patch.Conclusions:The combination of bupropion SR and varenicline did not demonstrate any smoking cessation advantage over varenicline monotherapy or the combination of bupropion SR and nicotine patch and therefore do not support the use of bupro-pion SR and varenicline over varenicline monotherapy.
