Prehospital care and interfacility transfer of trauma patients before reaching the emergency of a level-1 trauma care center.

Background: Management of trauma patients includes prevention, prehospital care, appropriate resuscitation at a hospital, definitive treatment, and rehabilitation. Timely and adequate care for a trauma patient is paramount, which can dramatically impact survival. This study was planned to assess the proportion of patients who failed to receive adequate prehospital care before reaching our institute. Materials and Methods: A retrospective study was conducted in the trauma and emergency department of a level-1 trauma center in eastern India from February to April 2022. The demographic profile, vital parameters, injury, mode of transport, travel duration, referring hospital, and any interventions as per airway/breathing/circulation/hypothermia were collected. Results: The records of a hundred-two patients who were brought to the trauma and emergency department in the study period were reviewed. Road traffic accident involving two wheelers was the leading cause of injury. Eighty-three percent of the patients were referred from other health centers, of which 49 were referred from district headquarters hospitals. Only three patients out of 14 had been provided with an oropharyngeal airway for whom endotracheal intubation was indicated. Only one among the 41 patients needing Philadelphia collar actually received. Sixteen patients were provided supplemental oxygen out of the 35 for whom it was indicated. Out of 68 patients in whom intravenous cannulation and fluid administration were indicated, only 35 patients had received it. Out of 31 patients with fractures, none were provided immobilization. Conclusion: The care of the trauma patients with respect to airway, breathing, circulation, and fracture immobilization was found to be grossly inadequate, emphasizing the need of structured and protocol based prehospital trauma care.

An Unusual Etiology of Severe Right Heart Failure Deserving of Wider Recognition.

A previously healthy 31-year-old man presented with worsening shortness of breath and a petechial rash. Echocardiography showed severe right-sided heart failure with midsystolic notching of the antegrade right ventricular outflow Doppler envelope suggesting pulmonary hypertension. An extensive work-up revealed scurvy, with a dramatic resolution of symptoms shortly after vitamin C supplementation.

PD-L1 Expression in Colorectal Carcinoma Correlates with the Immune Microenvironment.

INTRODUCTION/BACKGROUND: Colorectal carcinoma (CRC) is a common malignancy, with its diverse clinical, pathological, and molecular features. The immune microenvironment of a tumor comprises of interplay between various cells and molecules, and has a significant role in deciding the tumor behavior and overall prognosis. PD-L1 (programmed cell death ligand-1) has been implicated in the regulation of the tumor immune microenvironment (TIME). There is limited data regarding the correlation of PD-L1 expression with immune cell profile in CRCs, especially in the Indian setting. The study aimed to assess the PD-L1 expression in CRC tumor cells and its association with TIME, mismatch repair (MMR), and various other clinicopathological parameters. METHODS: This is a hospital-based, cross-sectional observational study. PD-L1 expression was assessed at the protein level by immunohistochemistry and mRNA level by qRT-PCR. Immune cell markers (CD4, CD8, CD20, FOXP3, and CD163) were interpreted using the ImageJ Fiji platform. RESULTS: Of the 104 cases, 21% were PD-L1 positive and were more common in right-sided CRCs. PD-L1 positive cases showed significantly higher concentrations of all T-cell subsets (CD4+ , CD8+ , and FOXP3+), CD20+ B-cells, and CD163+ macrophages were noted. No statistical significance was seen between PD-L1 expression with clinical profile, pathological subtype, grade or stage, mismatch repair status (proficient vs deficient), and survival. CONCLUSIONS: The present study showed a relatively lower frequency of PD-L1 in CRC from the Eastern Indian cohort. The immune cell concentration in the present study was calculated using image analysis-based objectivised methods. Significant correlation of PD-L1 expression in tumor cells with the tumor-infiltrating immune cells indicated its crucial role in the pathobiology of CRC especially by regulating the TIME. Considering the therapeutic implication of PD-L1 in various malignancies, it may be one of the crucial therapeutic targets in a proportion of cases.

Comparison of surgical site infection (SSI) between negative pressure wound therapy (NPWT) assisted delayed primary closure and conventional delayed primary closure in grossly contaminated emergency abdominal surgeries: a randomized controlled trial.

PURPOSE: NPWT has been tried in many surgical fields, including colorectal, thoracic, vascular, and non-healing wounds, for the prevention of SSI. However, its efficacy in the prevention of SSI-grade IV closed abdominal wounds is yet to be explored. METHODS: All patients with grade IV abdominal wounds were included in the study. They were randomized into the conventional arm and the VAC arm after confirming the diagnosis intra-operatively. The sheath was closed, and the skin was laid open in the postoperative period. In the VAC arm, the NPWT dressing was applied on postoperative day (POD)-1 and removed on POD-5. In the conventional arm, only regular dressing was done postoperatively. The skin was closed with a delayed primary intention on POD-5 in both arms. The sutures were removed after 7 to 10 days of skin closure. RESULTS: The rate of SSI (10% in the VAC arm vs. 37.5% in the conventional arm, p-value = 0.004) was significantly lower in the VAC arm, as were the rates of seroma formation (2.4% in the VAC arm vs. 20% in the conventional arm, p = 0.014) and wound dehiscence (7.3% vs. 30%, p = 0.011). The conventional arm had a significant delay in skin closure beyond POD5 due to an increased rate of SSI, which also led to a prolonged hospital stay (5 days in the VAC arm vs. 6.5 days in the conventional arm, p-value = 0.005). CONCLUSION: The VAC dressing can be used routinely in grade IV closed abdominal wounds to reduce the risk of SSI and wound dehiscence.

Prediabetes is an incremental risk factor for adverse cardiac events: A nationwide analysis.

Background and aims: Prediabetes is defined as a state of impaired glucose metabolism with hemoglobin A1c (HbA1c) levels that precede those of a diabetic state. There is increasing evidence that suggests that hyperglycemic derangement in prediabetes leads to microvascular and macrovascular complications even before progression to overt diabetes mellitus. We aim to identify the association of prediabetes with acute cardiovascular events. Methods: We utilized the National inpatient sample 2018-2020 to identify adult hospitalizations with prediabetes after excluding all hospitalizations with diabetes. Demographics and prevalence of other cardiovascular risk factors were compared in hospitalizations with and without prediabetes using the chi-square test for categorical variables and the t-test for continuous variables. Multivariate regression analysis was further performed to study the impact of prediabetes on acute coronary syndrome, acute ischemic stroke, intracranial hemorrhage, and acute heart failure. Results: Hospitalizations with prediabetes had a higher prevalence of cardiovascular risk factors like hypertension, hyperlipidemia, obesity, and tobacco abuse. In addition, the adjusted analysis revealed that hospitalizations with prediabetes were associated with higher odds of developing acute coronary syndrome (OR-2.01; C.I:1.94-2.08; P<0.001), acute ischemic stroke (OR-2.21; 2.11-2.31; p<0.001), and acute heart failure (OR-1.41; C.I.: 1.29-1.55; p<0.001) as compared to hospitalizations without prediabetes. Conclusions: Our study suggests that prediabetes is associated with a higher odds of major cardiovascular events. Further prospective studies should be conducted to identify prediabetes as an independent causative factor for these events. In addition, screening and lifestyle modifications for prediabetics should be encouraged to improve patient outcomes.

Impact of personal protective equipment on patient safety and health care workers.

Background: The study aims to assess the effect of personal protective equipment (PPE) on the physical and psychological well-being of health care workers (HCWs) and its impact on patient safety. Methods: After ethical approval, a 14-point questionnaire was circulated offline and online among the HCWs of ours institute, who were involved in performing invasive procedures while wearing a PPE. The responses were analysed using the SPSS software version 26. Results: Of 198 responses, the mean duration of PPE use was 4.6 ± 1.52 h. Seventy percent of respondents suggested <4 h of continuous use of PPE. Seventy-seven percent found difficulties during the procedures while wearing PPE and agreed to errors while performing a procedure. Poor visibility (95.5%), fogging (84.9%), communication difficulty (75.3%), sweating (74.2%), posture-related discomfort (56.1%) and poor concentration (51%) were major causes. Anxiety (39.9%) and fear of spreading an infection to the family (42.9%) were major psychological effects. Eighty percent of HCWs raised concern over the quality of PPE, N95 mask and eye protector. The HCWs felt the need to improve the quality of PPEs, use extra padding around the ears, sealing the N95 mask with adhesive tape, besides using sign language for communication for more safety. Fifty percent graded the procedure-related difficulty level >6 on a Likert scale of 1-10. Conclusion: PPE-related discomfort is common among the HCWs and could contribute to errors during an invasive procedure. Efforts to alleviate the physical and psychological well-being of the HCWs will be essential for reducing procedural error while wearing a PPE.

On-demand (SOS) analgesia through Transversus Abdominis Plane (TAP) catheter route for post-operative pain relief in Emergency Laparotomies-a non-randomised interventional study (STAPLE trial).

INTRODUCTION: This study aimed to compare the efficacy and safety of on-demand bupivacaine infusion via transversus abdominis plane (TAP) catheter in emergency laparotomy patients. METHODS: A non-randomised interventional study was conducted on patients undergoing emergency midline laparotomy. The intervention group received an on-demand infusion of 10 ml 0.5% bupivacaine through TAP catheters, whilst the control group received standard analgesic care. The primary outcome was the amount of rescue analgesic consumption. Secondary outcomes included the post-operative, measured by visual analogue scores (VAS), side effects, time to first flatus, post-operative nausea and vomiting, and pulmonary complications. RESULTS: One-hundred-twenty patients (58 in the TAP-SOS group, 62 in the control group) were included in the final analysis. The TAP-SOS group showed significantly reduced rescue analgesic requirement by 91% (p < 0.001) and lower VAS scores at 3, 6, 12, and 24 h (adjusted p < 0.00). Time to out-of-bed mobilisation was significantly shorter in the TAP-SOS group by 12.47 h (p < 0.001), and post-operative pulmonary complications were lower by 75% (p < 0.05). There were no significant differences in bowel recovery, catheter-related complications, or post-operative morbidity. No incidences of catheter-site infection were reported on follow-up; however, the catheter tip-culture was positive in 3 (5.17%) patients. CONCLUSION: On-demand bupivacaine infusion through a TAP catheter effectively reduced post-operative pain and opioid requirements in emergency laparotomy patients without complications. If an epidural is not an option, the TAP-SOS approach can be a helpful adjunct in implementing the ERAS protocol in an emergency since it allows for early ambulation and better pain management.

Comparison of laparoscopic port site skin closure techniques (CLOSA): transcutaneous suturing versus subcuticular sutures versus adhesive strips: a prospective single-blinded randomized control trial.

BACKGROUND: Cosmesis is an essential aspect of laparoscopic surgery. Various methods of skin closure techniques have been described. We conducted a study to evaluate the cosmesis and patient satisfaction with the scars three months after laparoscopic surgery using transcutaneous suture (TS) vs. adhesive strips (AS) and subcuticular suturing (SS). METHODS: A randomized, controlled, prospective study was conducted at AIIMS, Bhubaneswar. The included patients were randomly assigned among the three arms. The time for skin closure was measured. Wounds were assessed till discharge, at 14 days, one month, and three months. Cosmesis was measured by the Hollander Wound evaluation scale (HWES) for each incision separately, and patient satisfaction by a 10- point Visual analog scale (VAS). RESULTS: One hundred six patients were assessed for eligibility, and 90 patients were randomized. Three-month follow-up data was obtained from 83 patients (92.22%). Baseline characteristics were similar among the groups. Cosmetic outcome was assessed in 312 incisions across 83 patients, and 206 (66.03%) incisions had an HWE Score of 0, but there was no significant difference (p = 0.86). Patient satisfaction was highest in the TS group (TS = 1.29, SS = 1.79, AS = 2.04, p = 0.03). Time for skin closure was the least in the AS arm (41.4 secs, p = 0.00). Skin dehiscence was significantly more in the AS arm. Four (4.44%) patients had port site infections. CONCLUSION: This study demonstrates that skin closure by transcutaneous, subcuticular, or adhesive strip methods had comparable cosmetic outcomes at three months. However, the transcutaneous closure method showed better patient satisfaction and minimal post-operative complications.

Use of Technology to Improve the Adherence to Surgical Safety Checklists in the Operating Room.

BACKGROUND: Although checklists can improve safety in the operating room (OR), compliance with their use is variable. Use of a forcing function, a principle of human factors engineering, has not been reported earlier as a method of increasing checklist use. The authors conducted this study to determine the feasibility and effects of introducing a forcing function on OR surgical safety checklist implementation and adherence. METHODS: The authors developed and introduced the use of an electronic version of the surgical safety checklist on an Android application, provided on a personal device available in the OR. This application was linked by Bluetooth to electrocautery equipment, which could not be started before the electronic checklist was completed on the screen of the personal device. In the same OR, retrospective data from use of the traditional (paper-based) checklist were compared with data from the new electronic checklist for frequency of use, and completeness (percentage of all checklist items completed) at three stages of the surgical process-sign-in, time-out, and sign-out. RESULTS: The frequency of use was 100.0% for the electronic checklist, compared with 97.9% for the traditional checklist. The frequency of completeness was 27.1% for the traditional vs. 100.0% for the electronic (p < 0.001).The manual checklist's sign-out component was completed only 37.0% of the time. CONCLUSION: Although checklist use in some form was already high with the traditional checklist, completion rate was low and significantly increased with the use of the electronic checklist with a forcing function.

Risk Factors of Incident Kidney Stones in Indian Adults: A Hospital-Based Cross-Sectional Study.

Background The diverse manifestations of urolithiasis provide very interesting epidemiological data. This has prompted various studies to look into the etiopathogenesis of renal stones, which is believed to be multifactorial, both exogenous and endogenous. VDR Fok1 is a risk factor for renal stone formation and could cause the formation of renal stones through the mechanism of crystal induction and crystallization in the urine. While a few recent studies have shown the role of heavy metals like cadmium and lead in the formation of renal stones, the current knowledge is still insufficient. Methods This case-control prospective study was conducted in Guru Teg Bahadur (GTB) Hospital, a tertiary care facility in Delhi with 30 cases and 30 controls. Patients visiting the department of surgery between November 2011 and April 2013 were enrolled in the study. Cases were defined as patients with renal stones diagnosed on the basis of history and radiological investigations. Controls were selected from the patients admitted to the department of surgery for reasons other than renal stones. The study protocol was approved by the Institutional Ethical Committee of the University College of Medical Sciences, GTB Hospital, Delhi. Written informed consent was obtained from all patients. A structured questionnaire was used to collect data. Metal levels were analyzed by an atomic absorption spectrophotometer (Shimadzu Flame AA-680, Shimadzu Corp., Kyoto, Japan) at Delhi University. The vitamin D receptor gene was measured using genomic DNA. Horizontal agarose gel electrophoresis was used for the quantification of the genomic DNA. Results There were 30 cases and 30 controls in the study. Stress was more prevalent among cases (63%) compared to controls (36%). Nearly 83% of cases had the ff allele of the Vitamin D receptor gene compared to 46% of controls. The median arsenic and lead levels were higher among cases compared to controls. In the unadjusted model of logistic regression, we found stressed patients had three times higher odds of developing renal stones compared to non-stressed patients (OR (95% CI): 2.98 (1.04-8.52); p=0.04). Similarly, patients with higher blood concentrations of arsenic and lead had higher odds of developing renal stones compared to those with lower concentrations.  Conclusions There was a definitive role of heavy metals, including lead, cadmium, and arsenic, seen with renal stones. A significant association was seen between the ff allele of VDR polymorphism (Fok1 enzymes) and patients with renal stones. Other parameters, including male and stress factors, seem to have an important role in renal stone formation.

A National Perspective on the Impact of the COVID-19 Pandemic on Heart Failure Hospitalizations in the United States.

Nationwide data of the COVID-19 pandemic's impact on heart failure (HF) hospitalizations is lacking. We conducted this study to elucidate the impact of the COVID-19 pandemic on HF hospitalizations. Additionally, we assessed the differences in hospitalization characteristics during the pandemic and the impact that a concurrent diagnosis of COVID-19 has on various outcomes and predictors of inpatient mortality among patients admitted for HF. The National Inpatient Sample (NIS) database was queried for all hospitalizations with a primary diagnosis of HF between 2017 and 2020. Monthly HF hospitalizations were trended longitudinally over this period. Beginning April 1, 2020, concurrent COVID-19 infections were identified. Subsequently, we stratified HF hospitalizations between April 2020 and December 2020 (HF-2020) based on if concomitant COVID-19 was diagnosed, forming the HF-COVID+ve and HF-COVID-ve groups respectively. HF-2020 was also compared with prepandemic HF hospitalizations between April 2019 and December 2019 (HF-2019). Baseline characteristics were compared, and adjusted outcomes were obtained. During the initial COVID-19 surge in April 2020, HF admissions were reduced by 47% compared to January 2020. Following this decline, HF hospitalizations increased but did not reach prepandemic levels. HF-2020 admissions had an increased complication burden compared to HF-2019, including acute myocardial infarction (8.9% vs 6.6%, P < 0.005) and pulmonary embolism (4.1% vs 3.4%, P < 0.005) indicating a sicker cohort of patients. HF-COVID+ve hospitalizations had 2.9 times higher odds of inpatient mortality compared to HF-COVID-ve and an increased adjusted length of stay by 2.16 days (P < 0.005). A pandemic of the same magnitude as COVID-19 can overwhelm even the most advanced health systems. Early resource mobilization and preparedness is essential to provide care to a sick cohort of patients like acute HF, who are directly and indirectly effected by the consequences of the pandemic which has worsened hospitalization outcomes.

Surgical Site Infections in Patients of Periampullary Carcinoma Undergoing Delayed Bile Duct Division (COMBILAST) in Whipple's Procedure: A Prospective Cohort Study.

Surgical site infections (SSIs) following a pancreaticoduodenectomy have been a significant cause of morbidity and even mortality. A modified sequence of the Whipple procedure, using the COMBILAST technique, may reduce SSIs and the patient's hospital stay. This prospective cohort study included 42 patients undergoing Whipple's pancreaticoduodenectomy for a periampullary malignancy. The modified sequence pancreaticoduodenectomy technique, COMBILAST, was used to estimate the incidence of SSI and explore other advantages. Of the 42 patients, seven (16.7%) developed superficial SSIs, and two patients (4.8%) had an additional deep SSI. Positive intraoperative bile culture had the strongest association with SSI (OR: 20.25, 95% CI: 2.12, 193.91). The mean operative duration was 391.28 ± 67.86 min, and the mean blood loss was 705 ± 172 mL. A total of fourteen (33.3%) patients had a Clavien-Dindo grade of III or higher. Three (7.1%) patients died of septicemia. The average length of a hospital stay was 13.00 ± 5.92 days. A modified sequence of the Whipple procedure, using the COMBILAST technique, seems promising in reducing SSIs and the patient's hospital stay. As the approach is only a modification of the operative sequence, it does not compromise the oncological safety of the patient. Moreover, it has an added surgical advantage in reducing the chance of injury to the aberrant or accessory right hepatic artery.

Septic Shock Short-Term Outcomes in Patients With Psychiatric Disorders: Analysis From the National Inpatient Sample Database.

BACKGROUND: Major psychiatric disorders are associated with lower life expectancy primarily due to comorbid illnesses and suboptimal access to health care. Large-scale contemporary data in the United States on in-hospital mortality of patients with major psychiatric disorder and sepsis are lacking. OBJECTIVE: To describe the short-term outcomes of hospitalized patients with major psychiatric disorders and septic shock. METHODS: We performed a retrospective cohort study using the National Inpatient Sample database from 2016 to 2019 to identify septic shock hospitalizations in patients with versus without major psychiatric disorder (defined as schizophrenia and affective disorders). Baseline variables and in-hospital mortality trends were compared between the 2 groups. RESULTS: Out of 1,653,255 hospitalizations with septic shock identified between 2016 and 2019, 16.2% had a diagnosis of major psychiatric disorder as defined above. After adjusting for various patient-level and hospital-level demographics and coexisting clinical conditions in a multivariable logistic regression, the odds of in-hospital mortality in patients with any major psychiatric disorder were 0.71 times that of those without a diagnosis of psychiatric illness (95% confidence interval [CI], 0.69-0.73; P < 0.001). Similarly, when the disorders were divided into 2 categories for subanalysis, those with schizophrenia had 38% lower odds of dying compared to those without schizophrenia (adjusted odds ratio, 0.62; 95% CI, 0.58-0.66; P < 0.001). Those with affective disorders had 25% lower odds of in-hospital mortality than those without a diagnosis of an affective disorder (adjusted odds ratio, 0.75; 95% CI, 0.73-0.77; P < 0.001). The adjusted mean length of stay for those diagnosed with major psychiatric disorder was 0.38 days longer than those without significant psychiatric illness (95% CI, 0.28-0.49; P < 0.001). On the other hand, the mean hospitalization charges were $10,516 less for patients with a major psychiatric disorder compared to those without (95% CI, -$11,830 to -$9,201; P < 0.001). CONCLUSIONS: Hospitalized patients with major psychiatric disorder and septic shock had lower risk of short-term mortality. Further studies are needed to examine the reasons behind this lower in-hospital mortality risk.

A self-reported survey on the implementation of infection prevention and control elements in Indian hospitals, part of a HAI surveillance network: Results from 23 hospitals conducting a standardized IPC assessment.

BACKGROUND: Healthcare-associated infections (HAIs) are one of the most common adverse events in patient care that account for substantial morbidity and mortality. We evaluate the existing Infection Prevention and Control (IPC) practices in hospitals participating in the nationally representative HAI Surveillance network. METHODS: This cross-sectional survey was conducted in 23 hospitals across 22 states of India from October-2015 to September-2018 in the HAI surveillance network. The World Health Organization (WHO) IPC core components assessment tool for health-care facility level (IPCAT-H) was adapted from IPC assessment tool developed by US Centers for Disease Control and Prevention (US CDC) under the Epidemiology and Laboratory Capacity (ELC) Infection Control Assessment and Response (ICAR) Program. Mann-Whitney U test was used to calculate the significant difference between scores (P < .05). RESULTS: Amongst the participating hospitals, 7 were private sectors and 16 were public health care facilities. Infection IPCAT-H average score per multimodal strategy was less than 50% for programmed IPC activities (45.7); implementation of health care workers (HCWs) immunization programme (43.5%); monitoring and evaluation component (38.30%). CONCLUSIONS: There is potential for improvement in Human Resources, Surveillance of HAIs as well as Monitoring and Evaluation components.

Ligation of Intersphincteric Fistulous Tract vs Endorectal Advancement Flap for High-Type Fistula in Ano: A Randomized Controlled Trial.

BACKGROUND: This study aimed to compare the postoperative outcomes and success rate of the endorectal advancement flap and ligation of intersphincteric fistulous tract (LIFT) in high-type fistula in ano. STUDY DESIGN: This randomized control trial included patients with high-type fistula in ano of cryptoglandular origin. The primary endpoint was complete fistula healing at the end of 6 months. However, the patients were followed up for 2 years. Other parameters studied were perioperative complications, duration of surgery, postoperative pain, hospital stay in hours, continence, and quality of life at 6 months. RESULTS: A total of 84 patients were recruited (42 in each group). The healing rate in the LIFT arm was better than that in the endorectal advancement flap arm (76.2.% vs 54.7%, p = 0.039). Four patients in the endorectal advancement flap group and two in the LIFT group had flatus incontinence at the end of 6 months, but all were continent at 2 years. At the end of the first week, the Visual Analog Scale score and quality of life at 6 months were better in the LIFT arm (3.7 ± 1.16 vs 4.7 ± 0.81 and 0.7 vs 0.6, p < 0.05). The mean duration of surgery was significantly less in the LIFT group (46.43 ± 9.32 vs 89.29 ± 10.90 minutes). None had any postoperative complications, and >80% were discharged within 24 hours. CONCLUSIONS: The shorter operative duration, better quality of life at 6 months, and higher healing rate make LIFT a superior treatment option for high fistula in ano. However, studies with a large sample size will be needed to verify these results.

Ultrasound-guided selective peripheral nerve block compared with the sub-dissociative dose of ketamine for analgesia in patients with extremity injuries.

STUDY OBJECTIVE: To compare the analgesic efficacy of ultrasound-guided selective peripheral nerve block (PNB) and sub-dissociative dose ketamine (SDK) for management of acute pain in patients with extremity injuries presenting to the emergency department (ED). METHODS: This prospective, open-label randomized clinical trial was conducted in the ED of a tertiary care Institute. The patients were provided with either ultrasound-guided selective PNB or SDK. The primary outcome was a reduction in pain in numerical rating scale (NRS) by at least 3 points without rescue analgesia. The secondary outcomes were the need for rescue analgesia, adverse events, and patient satisfaction on either arm. RESULTS: A total of 111 patients with isolated traumatic extremity injuries were included in the final analysis. The NRS score was significantly lower in the PNB group compared to the SDK group at 30, 60,120, 180-, and 240-min post-intervention [group ∼ time interaction, F (5, 647) = 21.53, p ≤ 0.001]. All the patients in the PNB group exhibited primary outcome (NRS ≥3 reductions) at 30 min post-intervention compared with 36 (65%) in the SDK group [-1.02(-1.422,0.622)]. Rescue analgesia was required in 10 (18%) patients in the SDK group compared to none in the PNB group [0.663(0.277,1.050)]. The decrease in NRS score from baseline at 30 min was significantly higher in PNB groups compared to the SDK group [-2.166(-2.640, -1.692)]. The most common side effect reported in the SDK group was dizziness 35(64%), followed by nausea 15(27%). None of the patients in the PNB group reported any complications. Patient satisfaction was higher in the PNB group than SDK group. CONCLUSION: The study provides evidence that ultrasound-guided PNB is superior to SDK in terms of its analgesic efficacy in the management of acute pain due to extremity injuries and is associated with higher patient satisfaction. The need for rescue analgesia was significantly less in the PNB group. SDK was associated with a high incidence of dizziness and nausea.

A Dosimetric Study Comparing 3D-CRT vs. IMRT vs. VMAT in Left-Sided Breast Cancer Patients After Mastectomy at a Tertiary Care Centre in Eastern India.

Introduction Post-mastectomy radiation in left-sided breast cancer in women continues to pose a significant risk to the underlying lungs and heart. This study analyzed the difference in planning target volume (PTV) coverage and dose to the organs at risk (OAR) by using three different planning methods for the same patient - three-dimensional conformal radiotherapy (3D-CRT), intensity-modulated radiotherapy (IMRT), and volumetric-modulated arc therapy (VMAT). Material and methods Thirty-five left-sided breast cancer patients' post-mastectomy were included in this study, and three different plans for adjuvant radiation were created using 3D-CRT, IMRT, and VMAT. The prescribed dose was 50Gy in 25 fractions. Kruskal-Wallis analysis of variance (ANOVA) was done, followed by a pairwise t-test to establish a hierarchy of plan quality and dosimetric benefits. The plans were compared with PTV95, homogeneity index (HI), conformity index (CI), hotspot (V107%), left lung V20Gy, mean lung dose, heart V25Gy, mean heart dose, and integral dose (ID) to the body. Results Both VMAT and IMRT led to improved PTV95% coverage (95.63±1.82%, p=0.000 in VMAT; 93.70±2.16 %, p=0.000; 81.40±6.27% in 3D-CRT arm) and improved CI (0.91±0.06 in IMRT [p<0.05] and 0.96±0.02 for VMAT plans [p<0.05]) as compared to 3D-CRT (0.66±0.11), which was statistically significant on pairwise analysis. In contrast, the difference in HI and reduction in hotspots were not significantly different. Left lung V20 was statistically very different between the three arms with the highest values in IMRT (36.64±4.45) followed by 3D-CRT (34.80±2.24) and the most negligible value in VMAT (33.03±4.20). Mean lung dose was also statistically different between the three arms. There was a statistically significant difference in mean heart dose between the three arms on pairwise analysis. Both the inverse planning methods led to a statistically significant increase in low dose volume (V5 and V10) of the ipsilateral lung, opposite lung, and heart, and increased ID to the body excluding the PTV. Conclusion While both the inverse planning modalities led to increased coverage, better CI, and better HI and decreased high dose volumes in OARs, there was increased low volume irradiation of heart, lungs, and body with VMAT faring marginally better than IMRT in coverage and decreasing lung irradiation with comparable heart irradiation.

Lithotomy versus prone position for perianal surgery: a randomized controlled trial.

PURPOSE: Studies objectively comparing lithotomy and prone positions regarding surgeon comfort, ergonomics, patient comfort, and position related complications are scarce. METHODS: The patients posted for surgery of either fistula in ano, hemorrhoids, or were included in this study. Subjective Mental Effort Questionnaire (SMEQ) and Local Experienced Discomfort (LED) scale were used to score the level of mental and physical stress among the operating surgeon, assistants, and the scrub nurse. Other parameters studied were the exposure of the operative site, patient comfort level, and position-related complications. RESULTS: Thirty patients were operated in each position. Mean±standard deviation of jackknife prone vs. lithotomy surgeon SMEQ score (15.6±10.4 vs. 107.0±11.5, P<0.05) and LED score (1.8±1.5 vs. 6.7±0.5, P<0.05) were found to be statistically significant. Prone vs. lithotomy assistant SMEQ score (29.1±13.1 vs. 100.6±8.7, P<0.05) and LED score (4.6±1.1 vs. 7.4±0.8, P<0.05) were also found to be statistically significant. SMEQ (10.0±0.0 vs. 20.6±2.5, P<0.05) and LED scores (1.1±0.3 vs. 3.3±0.5, P<0.05) of scrub nurses and LED scores (2.5±0.5 vs. 6.3±0.7, P<0.05) of patients were also statistically significant. Exposure of the operative site was significantly better in the prone position (5.0 vs. 2.1, P<0.05). CONCLUSION: Significantly better SMEQ, LED, and exposure score suggests the superiority of jackknife prone position over the lithotomy in terms of significantly less mental and physical stress to the operating surgeon, assistant, and scrub nurse; better ergonomics, and excellent exposure.

The Clinico-histopathological Spectrum of Tumors and Tumor-Like Lesions in Adult Intussusception.

BACKGROUND: Intussusception is an uncommon cause of intestinal obstruction in adults. The etiology of this disease differs from the children. Thus, its management depends on the possible etiology and is different from pediatric cases. AIMS: We aimed to study the clinico-histopathological spectrum of the tumors and tumor-like lesions in the intussusception in adults. MATERIAL AND METHODS: A retrospective review of the adult (> 18 years) intussusception cases was performed. The clinical data and follow-up were obtained. The histopathology was reviewed along with the special stains and immunohistochemistry for ascertaining a histopathological diagnosis. RESULTS: Fifteen cases of adult intussusception were identified from 107 resected specimens of adult intestinal obstruction. The mean age was 44.5 years with a male/female ratio of 1.1:1. A definitive pathology could be ascertained in 80% of the cases (n = 12/15). Eight cases had benign non-neoplastic etiology (53.3%) (33.3% tumor-like lesions) while seven cases (46.7%) had neoplastic etiology (20% benign neoplastic; 26.7% malignant neoplastic). All cases of colonic or enterocolic intussusceptions were associated with neoplasia whereas 90% of the enteric intussusceptions occurred due to benign non-neoplastic causes.  CONCLUSIONS: Non-neoplastic causes are predominant in the enteric intussusceptions while neoplastic causes are more commonly associated with colonic or enterocolic intussusceptions. The post-operative histopathological examination concludes on the adequacy of the index surgery or the provision of further management if required.
