An autologous duraplasty in situ technique in the treatment of Chiari malformation Type I: a prospective study.

Our study aims to prospectively compare an autologous duraplasty in situ technique (IS group) with the synthetic dural graft duraplasty (SDG group) to clarify the effectiveness and superiority of the former in the treatment of patients with Chiari malformation type 1 (CM-I). 29 patients with CM-I were randomly assigned to either IS or SDG group. In both groups, a dissection from the occipital bone was performed. All procedures were performed by the same surgeon. The two duraplasty methods were compared in terms of surgical factors and complications. Data analysis was done for the baseline material, the neurological outcome and MRI-documented syrinx size at the 6month follow-up. 29 patients were enrolled in this study, 14 in the IS group and 15 in the SDG group. The results showed no significant difference in operation time (P = 0.916), amount of bleeding (P = 0.120), operation complications, hospitalization time (P = 0.854) and prognosis between the two groups. The hospitalization cost of IS group was 15,125 yuan less than that of SDG group (P < 0.05). The autogenous duraplasty in situ technique is a novel, simple, effective and economical surgical management for patients with CM-I.

Aortic remodelling based on false lumen communications in patients undergoing acute type I dissection repair with AMDS hybrid prosthesis: a substudy of the DARTS trial.

The Dissected Aorta Repair Through Stent Implantation trial demonstrated positive proximal aortic remodelling following aortic dissection repair with the AMDS Hybrid Prosthesis. In this study, we look to identify predictors of aortic remodelling following aortic dissection repair with AMDS including whether communications between branch vessels and the false lumen predict aortic growth. The Dissected Aorta Repair Through Stent Implantation trial included patients who underwent Acute DeBakey type I aortic dissection repair with the AMDS from March 2017-January 2019. Anatomic measurements were collected from original computerized tomography scans. Measurements were taken at zones 2, 3, 6, and 9. Patients were grouped based on the number of false lumen communications with the supra-aortic branch vessels or visceral branch vessels. Forty-seven patients were included in the original Dissected Aorta Repair Through Stent Implantation trial. Patients with false lumen communications with the supra-aortic branch vessels tended to have significant growth at zone 3(p = 0.02-0.0018), while greater numbers of visceral false lumen communications tended to predict aortic growth at zones 3 (p = 0.003), 6(p = 0.017-0.0087), and 9(p = 0.0016-0.0003). Aortic remodelling following Acute DeBakey type I aortic dissection repair using the AMDS may be predicted by local false lumen communications with branch vessels. Patients undergoing Acute DeBakey type I aortic dissection repair were more likely to experience significant aortic growth in zone 3 with more head vessel communications and in zones 3, 6, and 9 with more visceral false lumen communications. Predictors of aortic remodelling may help to guide initial surgical management for aortic dissection patients.

Carbon vs. Titanium Nails in the Treatment of Impending and Pathological Fractures: A Literature Review

Background: Long bones are commonly affected by musculoskeletal tumors, but they also represent one of the most frequent locations for metastases. The treatment is based on pain management and the prevention or stabilization of pathological fractures by intramedullary nailing. While titanium nails are probably the most used, carbon-fiber-reinforced (CFR) nails have emerged as a new option for oncological patients. The aim of this review is to compare titanium and CFR nails according to current findings. Methods: Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards were followed: a total of 1004 articles were identified and 10 were included. Results: Traditionally, titanium implants are highly valued for their optimal biomechanical properties and ease of insertion, facilitated by their radiopacity. However, the use of titanium poses challenges in radiotherapy due to interference with radiation dosage and the creation of ferromagnetic artifacts. Conversely, CFR implants have emerged as a recommended option for intramedullary fixation, due to their biomechanical and structural properties and their benefits during radiotherapy and follow-up monitoring X-ray. Conclusions: CFR nailing represents a promising advancement in the surgical management of oncological patients with long bone metastases. However, further studies are needed to increase surgeons’ confidence in their use.

Intraoperative Frozen Section Evaluation of Pancreatic Specimens and Related Liver Lesions.

Frozen sections are essential in the surgical management of patients, especially those with pancreatic masses, because frozen sections can provide answers intraoperatively and aid in treatment decisions. Pancreas frozen sections are challenging because of the small tissue size, processing artifacts, neoadjuvant treatment effects, and concurrent pancreatitis-like obstructive changes. The authors present a review of intraoperative evaluation of pancreatic specimens. To provide an approach to the diagnosis of pancreatic adenocarcinoma on frozen sections and to discuss commonly encountered pitfalls. Indications for pancreas frozen sections and specific margin evaluation will be discussed. We will also review frozen section diagnosis of subcapsular liver lesions and tumors other than metastases of pancreatic ductal adenocarcinoma. Data sources included a literature review and the personal experiences of the authors. The features for diagnosis of pancreatic adenocarcinoma include disordered architecture, glands at abnormal locations, and atypical cytology. It is important to be aware of the pitfalls and clues on frozen section. The evaluation of resection margins can be challenging, and in the setting of the resection of cystic tumors, the key is the diagnosis of high-grade dysplasia or cancer. Finally, it is vital to remember the differential diagnosis for subcapsular liver lesions because not all lesions will be metastases of adenocarcinomas or bile duct adenomas. Frozen sections remain a useful tool for the intraoperative management of patients with pancreatic tumors.

LIFE AND LIMB: THE SURGICAL MANAGEMENT OF FOOT COMPLICATIONS IN PEOPLE WITH DIABETES

IntroductionA common acute orthopaedic presentation is an ulcerated or infected foot secondary to diabetic neuropathy. Surgical debridement or amputation are often required to manage this complication of diabetes. International literature indicates that amputation may lead to further complications and an increased mortality rate. The aim of this study is to investigate the mortality rate associated with different surgical interventions. This will inform surgical management of patients presenting with acute foot complications from diabetes.MethodsThis is a retrospective review of patients with diabetic foot infections aged &gt;16 years attending Middlemore Hospital over a 10-year period (2012–2021). Clinical records were examined to determine whether patients were managed with no surgery, surgery but not amputation, or amputation. We recorded relevant baseline characteristics and comorbidities. Regression models were used to determine factors associated with mortality.ResultsOver the study period, 1260 patients were included in analysis. Patients were divided into three groups, a control group who received no surgical intervention (n=554), those receiving surgery but not amputation (n=269), and those who underwent amputation (n=437). After adjustment for potential confounders, mortality rates were significantly higher in those who underwent amputation compared with those who received surgical intervention without amputation. Survival probability at 1 year and 5 years was highest in the surgical intervention but not amputation group.ConclusionIt is clinically important that there is a lower mortality rate in patients who undergo surgical intervention without amputation. Treatment that aims to salvage the limb rather than amputate should be considered in management of patients with diabetic foot complications to optimise their care.

A Pilot Real-World Study of Ultrasonography Findings of Hidradenitis Suppurativa in Indian Patients and Its Diagnostic and Therapeutic Implications

Abstract Introduction Hidradenitis suppurativa (HS) is a multifactorial chronic inflammatory follicular disorder affecting apocrine gland-bearing areas of the body. We conducted an observational study to assess the ultrasonography (USG) findings in suspected HS patients at a tertiary care center in North India over 6 months. Aim The aim of this article was to study the USG findings in HS and correlate clinical and USG findings and scoring systems in HS with stage wise treatments. Materials and Methods All patients with a clinical suspicion of HS underwent an USG examination after clinical examination with a probe of 18 Hz frequency. Hurley's staging of patients was used to stage clinically, and the HS-SOS scoring and Doppler changes were assessed on USG. The treatment was revised in case of a change in the USG grading of severity. Results A total of 23 patients suspected of HS underwent USG evaluation, of which 12 (52%) were male and 9 (48%) were females, with the mean age being 25.3 years (range: 14–40 years). Based on the HS clinical grading, eleven patients (47.8%) were Hurley's stage I, six patients (26%) were stage II, and six patients (26%) were stage III. USG demonstrated that three patients had been misdiagnosed and had folliculitis (8.6%) and Crohn's disease (4.3%). Out of the remaining twenty patients with USG features of HS, based on HS SOS grading, three patients (15%) were grade I, seven (35%) were grade II, and ten (50%) were grade III. Of these, nineteen patients (95%) had axillary involvement, which was bilateral in 84% of cases. The other region affected was the groin in five patients (26.3%), while two had inframammary involvement (10.5%). On further characterization of the type of lesion, nodules (41; 40.6%) were the most common type of lesion by sinuses and thickened hair follicles in 31 (30.6%) patients. Based on USG findings, the management of 26% of patients was changed from medical to surgical intervention. Conclusion USG and Doppler are noninvasive bedside tools for the examination of HS, which helps to rule out differentials and delineate the extent and depth of the disease better by picking up subclinical lesions and help in determining disease activity by Doppler, which in turn helps in planning appropriate medical and surgical management of patients. It also identifies radiological parameters that help identify patients who could fail medical management.

Advancing cell-based therapy in sepsis: An anesthesia outlook.

Sepsis poses a health challenge globally owing to markedly high rates of morbidity and mortality. Despite employing bundle therapy over two decades, approaches including transient organ supportive therapy and clinical trials focusing on signaling pathways have failed in effectively reversing multiple organ failure in patients with sepsis. Prompt and appropriate perioperative management for surgical patients with concurrent sepsis is urgent. Consequently, innovative therapies focused on remedying organ injuries are necessitated. Cell therapy has emerged as a promising therapeutic avenue for repairing local damage to vital organs and restoring homeostasis during perioperative treatment for sepsis. Given the pivotal role of immune cell responses in the pathogenesis of sepsis, stem cell-based interventions that primarily modulate immune responses by interacting with multiple immune cells have progressed into clinical trials. The strides made in single-cell sequencing and gene-editing technologies have advanced the understanding of disease-specific immune responses in sepsis. Chimeric antigen receptor (CAR)-immune cell therapy offers an intriguing option for the treatment of sepsis. This review provides a concise overview of immune cell therapy, its current status, and the strides made in the context of sepsis research, discussing potential strategies for the management of patients with sepsis during perioperative stages.

Surgical Management and Short-Term Outcome of Patients with Posterior Fossa Tumor in All Age Groups: Our Perspective

Background: Different types of brain tumor can occur in the region of posterior fossa. Ependymoma, medulloblastoma and pilocytic astrocytoma occur mostly in children and rarely in adults. Brain metastases in adults are the most common malignancies at this site. Other tumors that occur in the posterior fossa are meningioma, schwannoma, hemangioblastoma, brain stem glioma and epidermoid tumors. Posterior fossa tumor has different treatment approaches and prognosis. So, an accurate diagnosis, surgical approaches, complication analysis and outcome assessment are mandatory. Objective: To evaluate the clinical aspects, surgical approach, role of preoperative shunt, post-operative complications, and short-term outcome of patients with posterior fossa tumor in different age groups. Methods: This cross-sectional observational study included 36 patients with posterior fossa tumors that were admitted and operated in the Neurosurgery Department of Rangpur Medical College Hospital between the period of November 2018 and June 2022. In each patient clinically diagnosis was confirmed by MRI of Brain with contrast followed by histopathology. Results: Out of 36 patients, 23(63.9%) patients were male and 13(36.1%) were female. Mean age was 18.01±13.95 SD years (minimum 6 months and maximum 45 years), more common in pediatric age group (36.1% &lt;10 years and 25% between 11-20 years). Common presentations were headache (91.6%), vomiting (83.3%) and ataxia (72.2%). Medulloblastoma (27.8%) and ependymoma (25%) were common histological types. Surgical outcome was excellent in 17 cases (47.2%), while poor in 5.6% and 19.4% patients died. There was no statistically significant association of surgical outcome with age (p=0.148) and sex (p=0.170). Suboccipital craniotomy was superior to other surgical procedures in terms of patient’s outcome (p=0.031). Ependymomas and Astrocytomas had better outcome (p=0.014). Conclusions: Surgical outcome is related to the operative approach and histology of the tumor in this study, but no significant association of patient’s outcome with age, sex and preoperative procedure.

Comparative long-term outcomes of airway resection and functional reconstruction for papillary thyroid cancer

IntroductionThe surgical management of patients diagnosed with papillary thyroid carcinoma (PTC) and tracheal invasion has been a subject of ongoing discussion, particularly regarding the approach to tracheal functional reconstruction. The objective of this study was to examine the surgical technique and prognosis of PTC patients with tracheal invasion. Materials and methodsThis study employed both univariate and multivariate Cox proportional hazard models to determine predictive factors that affect the progression-free survival (PFS) of PTC patients with tracheal invasion. Cox regression analysis was conducted by using R software version 4.3.1. ResultsIn our study, we included 247 patients with T4a PTC. Among them, 146 patients (59.1 %) were classified as Shin I, 57 patients (23.1 %) as Shin II-III, and 44 patients (17.8 %) as Shin IV. Patients in the Shin I group underwent shaving of the tumours in the airway. The preferred surgical methods in the Shin II, III and IV groups were window resection (66.7 %), sleeve resection (34.8 %) and partial tracheal resection and skin fistula (61.8 %), respectively. Multivariate analysis demonstrated that neither tracheal surgery nor reconstruction procedures had an impact on PFS in T4a PTC patients with tracheal invasion. The 5-year DSS rate for patients receiving radioiodine (RAI) therapy was 87.3 % (p = 0.033). ConclusionThis study confirmed that tracheal surgery and reconstruction methods had no impact on PFS in T4a PTC patients with tracheal invasion in different Shin groups. Furthermore, RAI therapy has the potential to increase the survival rate of patients with preoperative distant metastasis of T4a PTC.

Perioperative management of sarcopenia in patients undergoing major surgeries in Singapore: a modified delphi consensus.

Ageing population is a worldwide phenomenon with correspondingly higher proportion of older patients being treated in the hospital setting. Sarcopenia, which increases with age, has serious negative implications on health, hospitalization and overall postoperative recovery. There is no mutual consensus on perioperative management of sarcopenia in surgical patients in Singapore. The purpose of this study is to create greater clarity pertaining to the recognition of sarcopenia, the application of assessment criteria of sarcopenia and perioperative management of surgical patients in Singapore. A modified Delphi consensus consisting of a panel of experts from Singapore forming a multidisciplinary team, including surgeons, geriatricians, anesthesiologists, physiotherapists and dieticians. Eight recommendations were proposed by the steering committee. Literature search from MEDLINE, Embase and Scopus for articles up till June 2023 were performed to support recommendation statements. The expert panel voted on agreement to recommendation statements and graded the level of evidence supporting each statement through surveys to achieve consensus, set at 85% a priori. The panelists underwent two rounds of anonymized, independent voting before reaching consensus for all eight statements. After the first round, seven statements reached consensus, including the corresponding grading for level of evidence. The statement which did not achieve consensus was revised with supporting literature and after the second round of survey, all eight statements and level of evidence reached consensus, completing the Delphi process. These eight statements covered themes to (1) encourage the identification of sarcopenia, (2) guide pre-operative and (3) post-operative management of sarcopenia. With the varying approaches in perioperative management, poor understanding of and identification of sarcopenia can result in suboptimal management of sarcopenia in surgical patients. Given the abundance of evidence linking beneficial impact on recovery and post-operative complications with prudent management of sarcopenia, it is imperative and urgent to achieve awareness and consensus.

Abstract GS03-01: Magnetic Resonance Imaging and a 12-Gene Expression Assay to Optimize Local Therapy for Ductal Carcinoma In Situ: 5-year clinical outcomes of E4112

Abstract BACKGROUND. Advanced diagnostics such as magnetic resonance imaging (MRI) and gene-expression profiles are potentially useful to guide treatment in patients with ductal carcinoma in situ (DCIS). To evaluate these tests, we performed a prospective single arm multicenter study. We have previously reported the impact of MRI on surgical management of DCIS patients, and the effect of a 12-gene DCIS Score (DS) on radiotherapy (RT) use after wide local excision (WLE). We now report a pre-planned analysis of ipsilateral breast events (IBE) at 5-years. METHODS. Adult women with a core needle biopsy diagnosis of DCIS and eligible for WLE based on conventional imaging were registered following consent. All registered patients underwent breast MRI. Those still eligible, and willing, to receive WLE after appropriate follow-up biopsies underwent resection to free margins. DCIS sections were submitted to Exact Sciences for DS. Those with a low DS (&amp;lt; 39) were advised to omit RT; those with intermediate/high (inter/hi) DS (≥39) were advised to receive RT. All participants were monitored at 6-month intervals for any breast cancer event, and for survival. An IBE was defined as the first DCIS or invasive recurrence in the ipsilateral breast following the final WLE. Participants without IBE were censored by date of last contact or date of death for those who died. Follow-up was truncated at 5 years from WLE. Using data available as of 07-06-2023, Kaplan-Meier (K-M) curves were constructed to estimate the time-to-event distributions for subjects who received RT and for those who did not. The 5-year IBE rates and 95% confidence intervals (CIs) were estimated from K-M curves for all subjects with a DS (analogue of Intention to Treat [ITT] analysis), and for the subset who were compliant with their DS-based RT recommendation (Per Protocol analysis). The analyses were repeated for subgroups based on age at DCIS diagnosis (&amp;lt; 50 vs. ≥ 50). RESULTS. Of 339 women evaluable for the previously reported primary analysis (PMID 30653209), 171 (50.4%) underwent WLE with free surgical margins and had DS available for RT recommendations (ITT population). Of these, 7/82 low DS patients underwent RT, and 5/89 inter/hi DS patients declined RT; thus, the adherence to DS-based RT recommendations was 93%. At a median of 5 years of follow-up from final WLE, the ITT population experienced a total of eight IBE events (4.8%, 95% CI 2.4, 9.4) with 5-year IBE rates that were similar for participants with a low DS and for those with a inter/hi DS: 5.1% (95% CI: 1.9, 12.9) and 4.5% (95% CI 1.7, 11.7), respectively. Stratification by age did not alter these results: among women aged &amp;lt; 50 years (n=33), the IBE rate was 6.7% (95% CI 1.0, 38.7) for low DS and 5.6% (95% CI 0.8, 33.4) for inter/hi DS. Among women aged ≥ 50 years (n=138), the IBE rate was 4.7% (95% CI 1.5, 13.8) for low DS and 4.3% (95% CI 1.4, 12.7) for inter/hi DS. In the per-protocol analysis (N=159 adherent to RT recommendations), IBE rates were also similar for participants who had a low DS and no RT [5.5% (95% CI 2.1, 14.1)] and for those with inter/hi DS who received RT [4.8% (95% CI: 1.8% to 12.3%)]. Again, there was no discernible influence by age as categorized above. CONCLUSION. We report the first prospective data on use of DCIS Score for RT decisions, and 5-year IBE rates. We find that DS-based recommendations are followed by &amp;gt;90% of patients. Although the sample size is limited, the data are reassuring in that the IBE rate is similar between the low DS group treated with WLE alone and the inter/hi DS group treated with WLE and radiation, whereas prior studies have shown a marked difference in IBE rates by DS with excision alone. Therefore, this prospective trial provides strong evidence to support the omission of RT after surgery in DCIS patients with low DS, and its use in patients with intermediate/high DS.

Abstract ED11-02: Surgical controversies in IBC

Abstract In an era of treatment de-escalation, there remain questions regarding the optimal surgical management for patients with inflammatory breast cancer (IBC). For years, the standard surgical approach for patients with IBC has been modified radical mastectomy (MRM) (including complete axillary node dissection as a component of MRM) with delayed breast reconstruction. In the recent past, some authors have proposed the use of breast conserving surgery, sentinel lymph node mapping, skin-sparing mastectomy, and even immediate reconstruction as possibly appropriate procedures for the treatment of patients with IBC. In this educational session, we plan to review the available data to try and reach a conclusion on what surgical procedures appear to provide the best outcomes for patients with IBC.

Surgical Management of Patients with Distant Metastasized Adenoid Cystic Carcinoma of the Head and Neck.

Background: Adenoid cystic carcinoma (ACC) is a rare and malignant tumor of the salivary glands. Despite its slow-growing nature, this clinical entity is notorious for presenting with distant metastasis (DM) which significantly worsens patient outcomes. The role of surgery in patients with ACC and distant metastasis (DM) remains controversial. Methods: We conducted a retrospective analysis of 47 patients with ACC who underwent surgery for the primary tumor and presented with DM at baseline or developed DM during follow-up. We compared survival outcomes between patients with DM at baseline (Group A) and those who developed DM during follow-up (Group B). Results: The median overall survival (OS) for the entire cohort was 88%. Patients with DM at baseline (Group A) had significantly worse OS (51%) compared to those without DM at baseline (Group B) (91%; p=0.04). Local recurrence (LR) was associated with poor survival in both groups. However, salvage surgery for LR+DM was associated with improved OS compared to palliative treatment (100% vs 77%; p=0.79). Conclusion: Our findings suggest that surgery for the primary tumor of ACC may provide survival benefits in patients with DM. Salvage surgery should be considered particularly for patients who develop local recurrence and distant metastasis during follow-up.

The Impact of Neoadjuvant Chemotherapy on Axillary Surgical Management of Patients With Breast Cancer and Positive Axillary Lymph Nodes.

Sentinel lymph node biopsy (SLNB) is effective in patients with breast cancer (BC) and positive axillary lymph nodes undergoing neoadjuvant chemotherapy (NAC). However, the frequency with which axillary lymphadenectomy (ALND) can be avoided remains debated. This study aimed to identify patient populations that can benefit from this approach. The data of 195 consecutive patients with BC and positive axillary lymph nodes at diagnosis who underwent NAC were retrospectively analyzed. In all cases, the positivity of the lymph nodes was confirmed by cytological examination. Patients converted to ycN0 after NAC were considered eligible for SLNB. Indications for ALND were failed mapping, fewer than three SLNs recovered, and positive SLNs. Of 195 cN1 patients potentially eligible for SLNB, 71 (36.4%) remained clinically ycN+ after NAC and underwent elective ALND, while 124 (83.7%) converted to ycN0 after NAC and SLNB. The lymph node identification rate was 95.9% (119/124 patients) with three or more SLNs recovered in 83 cases (89.8%). One or two lymph nodes were recovered in 36 cases (30.2%). Nodal pathologic complete response (pCR) was found in 34/83 (40.9%) patients with three or more SLNs recovered. Considering all 195 patients initially included in the study, 55 patients (28.2%) achieved lymph node pCR after NAC. Nodal pCR varied based on hormone receptor and HER2 status, with rates ranging from 20.7% for ER+/HER2- patients to 95.3% for ER-/HER2+ patients (p<0.001). More than 80% of cN1 patients in our study were eligible for SLNB after NAC. ALND could be avoided in approximately 30% of cases, supporting the role of NAC in reducing the need for ALND among patients with lymph node metastases.

Laparoscopic cholecystectomy performed by a surgical care practitioner: a review of outcomes.

Surgical care practitioners (SCPs) are non-medical workers involved in various aspects of the management of surgical patients. The role includes assisting and performing surgical procedures. More than 60,000 laparoscopic cholecystectomies (LC) are performed annually in the UK. With ever-increasing pressure on waiting lists, it is important to look at fully utilising the skills of our entire workforce. We report what we believe is the first published series of LC performed by an SCP. A retrospective review of a prospectively collected database was performed. The primary outcome was any complication requiring intervention. Secondary outcomes were minor complications, operative time, length of stay, conversion and readmission. In total, 170 patients were operated on. Indications were biliary colic in 127 (74.7%), cholecystitis in 30 (17.6%) and pancreatitis in 13 (7.6%). Mean operating time was 65min (range 35-152min). Fifty-three operations were assisted by a consultant, 110 by a specialist or associate specialist grade (SAS) doctor and 7 by a core trainee (CT2). Some 139 (81.7%) patients were discharged on the day of surgery and 24 (14.1%) stayed one night in hospital. There were no major complications. Five patients required readmission, three with pain and two with port site infections. There were no conversions or transfusions required. There is a paucity of published data on surgical outcomes of procedures performed by SCPs. With a structured, supervised approach, SCPs could be trained to take on more complex procedures and further strengthen the surgical workforce. This study demonstrates that elective LC can be safely performed by an appropriately trained and supervised SCP.

Management of paediatric surgical patients during the COVID-19 pandemic: Our challenges

Purpose: Here we describe the challenges and procedures adopted to ensure safe paediatric surgery services during the COVID-19 pandemic at the paediatric surgery department in non-Covid-19 wing of Dhaka Medical College Hospital-1. Materials and Methods: Design: Retrospective study. Setting: Department of paediatric surgery in non-Covid- 19 wing of Dhaka Medical CollegeHospital-1, a tertiary care academic medical center in Dhaka, Bangladesh. Participants and duration: All patients who were admitted in the department of paediatric surgery in Dhaka Medical College Hospital-1 from March 1 through June 30, 2020. Methods: We identified patients with or without a rRTSARS- CoV-2 PCR receiving care at the department of paediatric surgery. The healthcare professionals were trained to clean, disinfect, use of PPEs, and other wastes were disposed of as per waste management protocols. Data collection &amp; analysis: Patient data were manually abstracted from the medical record for evaluation. Responses were analysed using Microsoft Excels &amp; SPSS, and presented as categorical data and percentages. Main outcome measures: We describe patient characteristics including demographics, presenting symptoms, type of treatment (Surgery vs Non Surgery), outcomes (morbidity &amp; mortality), hospital stay, and distance travelled for treatment. Results: A total of 320 paediatric surgical patients were included in this study, among all patients about 66.87% patients were male child and 79.06% patients required surgeries. There were 5 patients with confirmed COVID- 19, who were transferred to the Covid-Surgical unit. During this period, there were 4 (1.25%) children who died due to non-COVID related causes. In surgical group only 24(7.5%) patients developed postoperative complications. Length of hospital stay of 44 (13.75%) of non-surgical patients were less than 72 hours, whereas 141 (40.06%) of surgical patients were more than 72 hours. Majority of patients of both groups travelled more than 100 km distance for treatment. Conclusions: This corona crisis has provided an opening for rational health care and formulating global policies. So that in future such pandemics can be tackled more carefully and consistently with advancing knowledge and better preparation.

Racial disparities in disease-specific mortality and surgical management of patients with ductal carcinoma in situ with microinvasion.

Given persistent racial disparities in breast cancer outcomes, this study explores racial differences in disease-specific mortality and surgical management among patients with microinvasive ductal carcinoma in situ (DCIS-MI). The Surveillance, Epidemiology, and End Results Program was queried for patients aged 18+ years with DCIS-MI between January 1, 2010 and December 31, 2018. The study cohort was divided into non-Hispanic Black (NHB) and non-Hispanic White (NHW) patients. Disease-specific mortality was evaluated using Cox proportional hazards models. A total of 3400 patients were identified, of which 569 (16.7%) were NHB and 2831 (83.3%) were NHW. Compared with NHW patients, NHB patients had more positive lymph nodes (7.6% vs. 3.9% p < 0.001). In addition, NHB women were more likely to undergo axillary lymph node dissection (6.0% vs. 3.8%, p = 0.044) and receive chemotherapy (11.8% vs. 7.2%, p < 0.001). There were no racial differences in breast surgery type (p = 0.168), reconstructive surgery (p = 0.362), or radiation therapy (p = 0.342). Overall, NHB patients had worse disease-specific mortality (adjusted hazard ratio 2.13, 95% confidence interval [CI]: 1.10-4.14) with mortality risks diverging from NHW women after 3 years (6 years rate ratio [RR] 2.12, 95% CI: 1.13-4.34; 9 years RR 2.32, 95% CI: 1.24-4.35). NHB women with DCIS-MI present with higher nodal disease burden and experience worse disease-specific mortality than NHW women.

Bariatric Surgery Is Highly Effective and Underutilized in Patients with ADHD: A 5-Year Retrospective Cohort Study.

Obesity and ADHD have become increasingly common diagnoses. In the last decade, research has found that there is a high prevalence of obesity in patients with ADHD. The mainstays of management in the general population include lifestyle modifications, pharmacotherapies, and/or bariatric surgery. However, there is a lack of understanding of appropriate management of patients with both ADHD and obesity. We identified those with obesity for at least five consecutive years (BMI > 30) in the TriNetX database before separating into two groups based on the presence or absence of ADHD. We assessed both the distribution of treatment modalities and the change in average BMI over time in each of our four groups across 5years. Average BMI decreased over time in all groups, with the smallest change seen in the ADHD Pharmacology cohort (- 0.366kg/m2) and the largest in the ADHD Surgery group (- 8.532kg/m2). Average BMIs at the 5-year mark were significantly different. Our research found that pharmacological management of individuals with ADHD was only half as effective for individuals with ADHD than our control. Though surgical management of patients with ADHD is roughly 20 times more effective in managing obesity, it was not used as frequently in comparison to medication for management of weight.

A Comparative Analysis of Erector Spinae Plane Block Versus Conscious Sedation in Managing Percutaneous Cholecystostomy Pain.

This study investigates the efficacy of erector spinae plane block (ESPB) for managing perioperative and postoperative pain in patients undergoing percutaneous cholecystostomy (PC) for acute cholecystitis, particularly in high-risk elderly patients with extensive comorbidities and limited functional status. In a retrospective single-center study, 58 high-risk patients scheduled for PC were assessed. ESPB was administered to 23 patients, while 22 received conscious sedation. Pain intensity was measured using the numeric rating scale before any analgesic or ESPB administration, during the procedure and at 1 and 12h post-procedure and secondary outcomes included adverse effects and additional analgesic requirements. The ESPB group experienced significant pain reduction during and post-procedure compared to the conscious sedation group (p = 0.002). Procedure times were shorter (p = 0.015), and postoperative tramadol was less frequently needed in the ESPB group (p = 0.007). The incidence of nausea was also lower in the ESPB group (p = 0.001). No ESPB-related complications were reported. ESPB significantly alleviates perioperative and postoperative pain in PC patients, reducing additional analgesic use and side effects. It holds promise as a key component of pain management for high-risk surgical patients. Level 3, Non-randomized controlled cohort/follow-up study.

Surgical versus medical management of patients with primary hyperaldosteronism and indeterminate adrenal vein sampling: A 10-year experience of the Cleveland Clinic.

In patients with primary hyperaldosteronism (PA), adrenal vein sampling (AVS) can identify patients suitable for unilateral adrenalectomy. However, in AVS with an indeterminate aldosterone-to-cortisol lateralization (ACL) ratio of 3.0-4.0, clinical guidance is unclear. The authors screened all patients undergoing AVS at the Cleveland Clinic from October 2010 to January 2021 and identified 18 patients with indeterminate ACL results. Ten underwent adrenalectomy and eight continued medical management. The surgical group was younger (58.5 vs. 68 years, p=.17), and more likely to have a unilateral imaging adrenal abnormality (90% vs. 38%, p=.043) and a lower contralateral suppression index (0.63 vs. 1.1, p=.14). Post-treatment, the surgical group had a significant reduction in diastolic blood pressure (-5.5mmHg, p=.043) and aldosterone (4.40 vs. 35.80ng/mL, p=.035) and required fewer anti-hypertensive medications (2 vs. 3, p=.015). These findings may support the benefit of adrenalectomy in a select group of patients with indeterminate ACL.
