Clinical Features of Cardiac Calcified Amorphous Tumor: A Narrative Review.

A cardiac calcified amorphous tumor (CAT) is a non-neoplastic cardiac mass composed of calcified nodules surrounded by amorphous fibrous tissue in a context of degeneration and chronic inflammation. Although CAT cases are increasingly reported, its clinical manifestation remains unclear. We aimed to conduct a narrative review of CAT and identify its clinical characteristics. We conducted a comprehensive literature search using PubMed, with the keyword "Cardiac Calcified Amorphous Tumor" to identify relevant articles. A total of 113 articles published between 1997 and 2022 were retrieved. The clinical features allowing for assess patient background, differences with and without end-stage renal disease (ESRD), symptom-related factors, risk factors for embolism caused by CAT, and features of CAT, such as shape, location, mobility, pathology, and treatment, were statistically analyzed in 106 criteria-matched cases. The mean patient age was 60.2 ± 18.6 years, with 45 men and 61 women. Of the data collected from 21 countries, 52 patients were from Japan. Mobile CAT was more common in the chronic renal failure group. Linear, club-shaped, and spindle-shaped CAT tended to be mobile and more common in the ESRD group as well as located in the mitral valve region. The shape, mobility, location, and underlying mechanism of CAT depended on the presence or absence of ESRD. The risk of embolism was considered high because mobile CAT was more common in the ESRD group, and CAT originated in the mitral valve region. Hence, early diagnosis based on periodic examination in patients with ESRD and aggressive surgical treatment are necessary.

Abstract PO3-09-12: Exploring Gender-Specific Patterns of Breast Cancer in Brazil: A Comparative Epidemiological Study

Abstract Introduction: Male breast cancer constitutes approximately 1% of all breast cancer cases, and limited studies have focused on this population, resulting in a lack of understanding of the disease in men. This study aims to describe the epidemiological profile of male breast cancer in Brazil and compare it with female breast cancer. Methods: A comprehensive observational cross-sectional study was conducted using retrospective data from the DATASUS database (SISCAN/Cancer Information System) spanning the period from 2017 to 2021. Male and female patients diagnosed with breast cancer (ICD C50) during this period were included. Statistical analysis involved absolute values, percentages, and a 95% confidence interval (p < 0.05). Results: Analysis of the study period revealed 4,326 cases (1.8%) of male breast cancer and 236,597 cases (98.2%) of female breast cancer in Brazil. The southeast region had the highest concentration of cases for both sexes, while the northeast region showed a higher prevalence in males (p < 0.0004). Noteworthy findings include a higher mean age among males (59.5 years) compared to females (55.7 years) and a higher prevalence of advanced stages at diagnosis in males (72.8% vs. 59.3%). Diagnostic approaches, subtype distribution, and treatment modalities also differed between the genders. Conclusions: Male breast cancer presents with more advanced stages at diagnosis compared to females, necessitating more aggressive surgical interventions. However, males benefit from earlier initiation of treatment. These findings contribute to a better understanding of male breast cancer, enabling the development of tailored management strategies for this unique patient population.

Spontaneous union of neglected proximal pole scaphoid fracture: A case report

Scaphoid fractures are the most common carpal bone fractures and usually occur due to trauma, typically a fall on an outstretched hand. The scaphoid bone is integral to wrist biomechanics, linking the proximal carpal row to the distal row. Neglected scaphoid fractures can lead to significant long-term complications, with degenerative changes likely to occur. The most common consequence of a neglected scaphoid fracture is known as scaphoid non-union advanced collapse, which typically begins within five years following the injury. It is widely accepted that scaphoid fractures, in general, should be treated to avoid long-term complications. Many surgeons aggressively treat proximal pole fractures with surgical fixation due to the high risk of avascular necrosis. Although some surgeons may consider a period of immobilization, none would argue against the need for treatment of proximal pole fractures, either through immobilization or surgical fixation. In this case, we present an instance of spontaneous union of a neglected proximal pole fracture non-union in a mature adult. This report aims to provide awareness of the possible spontaneous union of neglected proximal pole scaphoid fracture. It also challenges the call for acute aggressive surgical intervention in such fractures. Radiographs and magnetic resonance imaging scan images before and after union are presented, along with a review of the available literature.

Surgical management of lower limb radiculopathy following acute singe-level osteoporotic vertebral fracture of lower lumbar spine in geriatric patient: a retrospective study

BackgroundRadiculopathy of the lower limb after acute osteoporotic vertebral fractures (OVFs) in the lower lumbar spine is uncommon in geriatric patients. Moreover, surgical intervention is generally recommended in patients who are irresponsive to conservative treatment. Determining an optimum surgical strategy is challenging considering the poor general condition of this population. Thus, herein, we established an algorithm for surgically managing this clinical scenario, hoping to provide a reference for making a surgical decision.MethodsWe retrospectively studied patients who suffered from new-onset radiculopathy of the lower limb after acute single-level OVFs in the lower lumbar spine and eventually underwent surgical intervention at our department. Information on the demographics, bone quality, AO spine classification of the vertebral fracture, pre-existing degenerative changes, including foraminal stenosis and lumbar disc herniation, and surgical intervention type was collected. Additionally, clinical outcomes, including preoperative and postoperative visual analog scale (VAS) scores for back and leg pain, Oswestry disability index (ODI), and MacNab criterion for response to surgery, were evaluated.ResultsFrom September 2019 to December 2021, a total of 22 patients with a mean age of 68.59 ± 9.74 years were analyzed. The most involved vertebra was L5 (54.5%), followed by L4 (27.3%) and L3 (18.2%). Among the 22 patients, 15 (68.2%) were diagnosed with the A1 type fracture of AO classification, and among them, 11 (73.3%) were characterized by the collapse of the inferior end plate (IEP). Three patients (13.6%) suffered from A2-type fractures, whereas four patients (18.2%) suffered from A3-type fractures. Pre-existing degenerative changes were observed in 12 patients (54.5%) of the patients. A total of 16 patients (72.7%) were treated by percutaneous kyphoplasty (PKP). Additionally, three patients underwent posterior instrumentation and fusion, two patients underwent a secondary endoscopic foraminoplasty, and one patient underwent a secondary radiofrequency ablation. The mean follow-up period was 17.42 ± 9.62 months. The mean VAS scores for leg and back pain and ODI decreased significantly after the surgery (P < 0.05). The total satisfaction rate at the last follow-up was 90.9% per the Macnab criterion.ConclusionPatients with OVFs in the IEP are predisposed to suffer from radiculopathy of the lower limb. PKP alone or in combination with other minimally invasive surgical strategies is safe and effective in treating stable fractures. Additionally, aggressive surgical intervention should be considered in patients with unstable fractures or severe foraminal encroachment.

The changing trend of fungal infection in invasive rhinosinusitis in the COVID era

ABSTRACT Background: SARS-COV virus operates as a significant risk factor for invasive fungal aspergillosis and mucormycosis. Successful management of this fulminant infection requires early recognition of the disease and aggressive medical or surgical interventions to prevent the high morbidity and mortality associated with the disease process. Aims and Objective of the Study: 1. To isolate and identify different species of fungi among acute rhinosinusitis patients. 2. To assess the association of risk factors causing fungal rhinosinusitis. 3. To assess the changing trend in fungal rhinosinusitis during the COVID era. Material and Methods: This is a retrospective observational study conducted from May 2020 to October 2022, attending the ENT department and relevant data were collected from the medical records department of ABVIMS and Dr RML Hospital, New Delhi, a Tertiary Care Referral Centre in India. The major risk factors studied were age, gender, COVID-19 infection and underlying diseases (such as diabetes mellitus, ischaemic heart disease, hypertension, malignancies, chronic kidney DISEASES, etc.); details of corticosteroid use of all patients were recorded in the datasheet. The pandemic data was divided into three distinct time periods/waves/eras, i.e., first, second, and third waves, each of which included ten months, to examine the changing trend in fungal rhinosinusitis in the pandemic era of COVID-19. Results: A total of 412 patients out of which 236 patients were clinically diagnosed with fungal sinusitis based on revised EORTC criteria. The most common site involved was the orbit with paranasal sinus and eye 86/236 (36.4%), followed by involvement of nasal and paranasal sinus alone 68/236 (28.8%). The most prevalent age range affected was 40 to 50 years. The most commonly associated comorbidity was diabetes mellitus (DM) in 176 (74.5%), followed by head and neck malignancies in 22 (9.32%) patients. Thirty-eight (50.6%) Rhizopus species and 18 (24%) Aspergillus flavus were the most common isolated fungal species on culture, followed by Mucor spp. 14 (18.6%) and Aspergillus fumigatus 5 (6.6%) in the period. In the second wave of COVID, there was a surge in Zygomycetes cases 36 (45%) and after the second wave, the Aspergillus cases increased by 14 (19%) during Jan-Oct 2022. Conclusion: With the continuing coronavirus pandemic, there is an unprecedented and discernible rise in the prevalence of acute invasive fungal sinusitis certainly a spike in cases of Aspergillus infection was observed, probably due to unprecedented usage of Amphotericin B for the treatment of mucormycosis during the third wave This underlines the importance of the need to tailor our treatment protocol as per the etiological agents hence the right antifungal drugs combined with urgent surgical procedures on a case-to-case basis may certainly increase the chances of survival.

Abstract 1001: Association between oral cancer screening and knowledge of head and neck cancer symptoms and risk factors among Arab Americans

Abstract Background: Head and neck cancer (HNC) has been increasingly affecting individuals of different ages, significantly contributing to the annual cancer burden in the US. While most HNC cases present at late-stages and are more likely to require aggressive surgical interventions with higher mortality, those who present with premalignant clinical signs or early-stages have a 5-year survival of 70%-90%. Moreover, current HNC public awareness is poor with lack of data on cultural and ethnic minorities. This study evaluated the association between oral cancer screening (OCS) recommendation and receipt and HNC symptoms and risk factors knowledge among Arab Americans in Michigan. Methods: This was a cross-sectional study of adult Arab Americans conducted between March and July 2023. Surveys were available in English and Arabic per participants preference. Outcome variables were knowledge of three main HNC risk factors—alcohol, cigarette smoking, and HPV— and four of the most common HNC symptoms—nonhealing oral ulcers, dysphagia/odynophagia, voice changes and neck/throat masses—defined as yes/no. OCS was captured as receiving provider-given recommendation for screening and undergoing a screening test (yes/no). Multivariable logistic regression models estimated the associations between OCS and HNC symptoms and risk factor knowledge adjusting for socioeconomic factors. Results: A total of 295 respondents were included in the study, 9% had received recommendation for OCS and 11% had undergone a screening test. In adjusted models, respondents who did not correctly identify nonhealing oral ulcers (aOR=0.20; 95% CI 0.06-0.67) as HNC symptoms or HPV (aOR=0.15; 95% CI 0.04-0.55) as risk factor of HNC were less likely to have received provider-given recommendation for OCS compared to those who identified the symptom and risk factor. Similarly, respondents who did not correctly identify nonhealing oral ulcers (aOR=0.13; 95% CI 0.04-0.42), dysphagia or odynophagia (aOR=0.22; 95% CI 0.07-0.70), voice changes (aOR=0.27; 95% CI 0.09-0.81), and neck/throat masses (aOR=0.24; 95% CI 0.06-0.91) as HNC symptoms or HPV (aOR=0.07; 95% CI 0.02-0.29) and alcohol (aOR=0.17; 95% CI 0.05-0.58) as HNC risk factors were less likely to have undergone OCS compared to those who identified the symptoms and risk factors. Conclusion: Respondents who reported limited knowledge of HNC symptoms and risk factors were less likely to be exposed to screening recommendations or testing. Combining screening with education on premalignant and early-stage clinical signs and risk factors might facilitate reduction of HNC incidence and late diagnosis. Further interventions are needed to increase Arab Americans education and identification of high-risk groups by their providers. As HNC screening efficacy remains controversial, future efforts should be directed towards deepening our understanding in this area.

Acute type a aortic intramural hematoma complicated with preoperative hemopericardium: early and late surgical outcome analyses

BackgroundAcute type A aortic intramural hematoma (ATAIMH) is a variant of acute type A aortic dissection (ATAAD), exhibiting an increased risk of hemopericardium and cardiac tamponade. It can be life-threatening without emergency treatment. However, comprehensive studies of the clinical features and surgical outcomes of preoperative hemopericardium in patients with ATAIMH remain scarce. This retrospective study aims to investigate the clinical features and early and late outcomes of patients who underwent aortic repair surgery for ATAIMH complicated with preoperative hemopericardium.MethodsWe investigated 132 consecutive patients who underwent emergency ATAIMH repair at this institution between February 2007 and August 2020. These patients were dichotomized into the hemopericardium (n = 58; 43.9%) and non-hemopericardium groups (n = 74; 56.1%). We compared the clinical demographics, surgical information, postoperative complications, 5-year cumulative survival rates, and freedom from reoperation rates. Furthermore, multivariable logistic regression analysis was utilized to identify independent risk factors for patients who underwent re-exploration for bleeding.ResultsIn the hemopericardium group, 36.2% of patients presented with cardiac tamponade before surgery. Moreover, the hemopericardium group showed higher rates of preoperative shock and endotracheal intubation and was associated with an elevated incidence of intractable perioperative bleeding, necessitating delayed sternal closure for hemostasis. The hemopericardium group exhibited higher blood transfusion volumes and rates of re-exploration for bleeding following surgery. However, the 5-year survival (59.5% vs. 75.0%; P = 0.077) and freedom from reoperation rates (93.3% vs. 85.5%; P = 0.416) were comparable between both groups. Multivariable analysis revealed that hemopericardium, cardiopulmonary bypass time, and delayed sternal closure were the risk factors for bleeding re-exploration.ConclusionsThe presence of hemopericardium in patients with ATAIMH is associated with an elevated incidence of cardiac tamponade and unstable preoperative hemodynamics, which could lead to perioperative bleeding tendencies and high complication rates. However, patients of ATAIMH complicated with hemopericardium undergoing aggressive surgical intervention exhibited long-term surgical outcomes comparable to those without hemopericardium.

An injectable in situ hydrogel platform for sustained drug release against Glioblastoma

Glioblastoma (GBM) is the most common and malignant primary brain tumor in adults. Despite aggressive surgical and medical treatments, the prognosis for patients with GBM remains grim and tumor recurrence is inevitable. Long-acting localized chemotherapy can not only reduce systemic toxicity, but also maintain chemotherapeutic concentration at the tumor sites over prolonged duration, thereby having the potential to improve GBM treatment. The present research aims to investigate an injectable in situ hydrogel made up of biopolymers collagen and hyaluronic acid that are abundant in the brain for sustained chemotherapy against GBM. Temozolomide (TMZ), an alkylating antineoplastic agent and the first-line treatment for GBM, was selected as the model chemotherapeutic and encapsulated in liposomes to facilitate deep tumor penetration. Whether the presence of liposomes affected gelling behavior and rheological properties of the collagen-based hydrogel system was investigated. Moreover, the in vitro efficacy of the TMZ-liposome/hydrogel composite was studied using a 3D spheroid GBM model. The developed TMZ-liposome/hydrogel composite gelled within 1 min at 37 °C and demonstrated sustained payload release and deep tumor penetration in the 3D GBM spheroids. More importantly, the composite remarkably inhibited glioma cell growth. These results showed that the developed liposome/in situ hydrogel composite is a promising drug delivery platform for the long-term localized treatment of GBM.

Atypical Mycobacterial Infections of the Spine: Evaluation and Management.

Atypical mycobacterial infections of the spine can be difficult to treat and represent a subset of the vertebral osteomyelitis and diskitis spectrum often requiring early and aggressive surgical intervention. The purpose of this review is to improve the understanding of and approach to disease management from the perspective of the spine surgeon. Debridement or excision of the affected levels may be necessary to decrease mycobacterial loads and restore biomechanics. A close relationship with the patient's internal medicine and infectious disease specialists should be maintained to ensure disease eradication or remission. Long-term suppressive antibiotic therapy may be required for infection control. Atypical mycobacterial spine infections are rare, complex, and difficult to eradicate. Our institution proposes a collaborative effort among the spine surgeon, infectious disease specialists, and internal medicine specialists to best approach the work-up, diagnosis, and treatment of these infections.

Practical Review of Necrotizing Fasciitis: Principles and Evidence-based Management.

Necrotizing fasciitis is a severe, life-threatening soft tissue infection that presents as a surgical emergency. It is characterized by a rapid progression of inflammation leading to extensive tissue necrosis and destruction. Nonetheless, the diagnosis might be missed or delayed due to variable and nonspecific clinical presentation, contributing to high mortality rates. Therefore, early diagnosis and prompt, aggressive medical and surgical treatment are paramount. In this review, we highlight the defining characteristics, pathophysiology, diagnostic modalities, current principles of treatment, and evolving management strategies of necrotizing fasciitis.

Role of Surgery in the Outcome Difference of Gastroschisis between High-income and Lowmiddle- income Countries: A Review

Gastroschisis is a major congenital abdominal wall defect where the abdominal viscera comes out through a gap right to the umbilicus. The management of gastroschisis requires prompt and aggressive medical and surgical intervention immediately after birth. However, there is a notable disparity in mortality rates between developed countries and LMICs. Despite various surgical technique adjustments, LMICs still suffer from a high mortality rate, with certain centers reporting a 100% mortality rate. This article seeks to examine the literature and evaluate the impact of surgical techniques on the outcome of gastroschisis.&#x0D; DS (Child) H J 2022; 38(2): 103-106

Conservative treatment outcome for Achilles tendon re-rupture occurring in the subacute phase after primary repair.

Until now, a treatment protocol for Achilles tendon re-rupture (ATRR) occurring in the postoperative period 5-12weeks following primary Achilles tendon repair has not been established. We refer to this time frame as the subacute postoperative phase, and the objective of this study was to assess the efficacy of conservative treatment for subacute ATRR in this phase. We conducted a retrospective review of 390 cases (385 patients) who had undergone primary Achilles tendon repair using the 4-strand Krachow method between January 2010 and August 2021. All patients were subjected to more than 12months of follow-up and were categorized into two groups based on the presence of subacute ATRR: Group 1 comprised 370 cases without ATRR, while Group 2 comprised 20 cases with ATRR. Following confirmation of ATRR, we immediately applied a below-knee cast in an ankle plantar flexed position (25°-30°), followed by bracing according to the same rehabilitation plan used for the primary repair. After administering conservative treatment to the patients with ATRR, we compared several outcome parameters between the two groups, including isokinetic plantar flexion power measured using a dynamometer, time required for a single heel raise (t-SHR), time needed for ten repetitive SHRs (t-SHR10), Achilles Tendon Total Rupture Score (ATRS), and Foot and Ankle Ability Measure (FAAM) scores. The baseline timepoints for Groups 1 and 2 were the dates of the primary repair and the re-injury event. After primary Achilles tendon repair, subacute ATRR occurred in 5.1% of patients. There were no significant differences between the groups in terms of t-SHR and t-SHR10 (P = 0.281, 0.486). Similarly, the isokinetic dynamometer measurements revealed no significant differences in peak torque for plantar flexion at angular velocities of 30°/s and 120°/s, both in absolute values and as a percentage of the contralateral side, between the groups (P > 0.05 for each). However, ATRSs were significantly lower in Group 2 compared to Group 1 before 6months (P < 0.05), as were FAAM-Activities of Daily Living scores at 6months (P < 0.05). After 12months, there were no significant differences in these scores between the two groups (both P > 0.05). Conservative treatment for subacute ATRR following primary Achilles tendon repair yields clinical outcomes comparable to those without ATRR. Therefore, we recommend that surgeons consider relying on the patient's natural healing capabilities rather than opting for aggressive surgical interventions, as expediting such operations may be unnecessary for subacute injuries.

Incidence and Management of Hardware-Related Wound Infections in Spinal Cord, Peripheral Nerve Field, and Deep Brain Stimulation Surgery: A Single-Center Study

Introduction: Neuromodulation using deep brain stimulation (DBS), spinal cord stimulation (SCS), and peripheral nerve field stimulation (PNFS) to treat neurological, psychiatric, and pain disorders is a rapidly growing field. Infections related to the implanted hardware are among the most common complications and result in health-related and economic burden. Unfortunately, conservative medical therapy is less likely to be successful. In this retrospective study, we aimed to identify characteristics of the infections and investigated surgical and antimicrobial treatments. Methods: A retrospective analysis was performed of patients with an infection related to DBS, SCS, and/or PNFS hardware over an 8-year period at our institution. Data were analyzed for type of neurostimulator, time of onset of infection following the neurosurgical procedure, location, and surgical treatment strategy. Surgical treatment of infections consisted of either a surgical wound revision without hardware removal or a surgical wound revision with partial or complete hardware removal. Data were further analyzed for the microorganisms involved, antimicrobial treatment and its duration, and clinical outcome. Results: Over an 8-year period, a total of 1,250 DBS, 1,835 SCS, and 731 PNFS surgeries were performed including de novo system implantations, implanted pulse generator (IPG) replacements, and revisions. We identified 82 patients with infections related to the neurostimulator hardware, representing an incidence of 3.09% of the procedures. Seventy-one percent of the patients had undergone multiple surgeries related to the neurostimulator prior to the infection. The infections occurred after a mean of 12.2 months after the initial surgery. The site of infection was most commonly around the IPG, especially in DBS and SCS. The majority (62.2%) was treated by surgical wound revision with simultaneous partial or complete removal of hardware. Microbiological specimens predominantly yielded Staphylococcus epidermidis (39.0%) and Staphylococcus aureus (35.4%). After surgery, antimicrobials were given for a mean of 3.4 weeks. The antimicrobial regime was significantly shorter in patients with hardware removal in comparison to those who only had undergone surgical wound revision. One intracranial abscess occurred. No cases of infection-related death, sepsis, bacteremia, or intraspinal abscesses were found. Conclusion: Our data did show the predominance of S. epidermidis and S. aureus as etiologic organisms in hardware-related infections. Infections associated with S. aureus most likely required (partial) hardware removal. Aggressive surgical treatment including hardware removal shortens the duration of antimicrobial treatment. Clear strategies should be developed to treat hardware-related infections to optimize patient management and reduce health- and economic-related burden.

Impact of azole antifungal treatment on outcome in acute invasive fungal rhinosinusitis with orbitocranial involvement: a surgical perspective.

To provide real-life data on azole treatment outcomes and the role of surgery in the current management of invasive fungal rhinosinusitis complicated by orbitocranial fungal infection (OCFI). Data was collected retrospectively from a chart review from four participating centers and a systematic literature review. The study group included patients with OCFI treated with azole antifungals. The control cases were treated with other antifungal agents. The cranial and orbital involvement degree was staged based on the imaging. The extent of the surgical resection was also classified to allow for inter-group comparison. There were 125 patients in the azole-treated group and 153 in the control group. Among the patients with OCFI cranial extension, 23% were operated on in the azole-treated group and 18% in the control group. However, meninges and brain resection were performed only in the controls (11% of patients) and never in the azole antifungals group. Orbital involvement required surgery in 26% of azole-treated cases and 39% of controls. Despite a more aggressive cranial involvement, azole-treated patients' mortality was significantly lower than in controls, with an OCFI-specific mortality rate of 21% vs. 52%. A similar, though not statistically significant, trend was found for the extent of the orbital disease and surgery. Despite less aggressive surgical intervention for cranial involvement, OCFI patients treated with azoles had a higher survival rate. This finding suggests we may improve morbidity with a more conservative surgical approach in conjunction with azole treatment. The same trend is emerging for orbital involvement.

Outcomes of Head and Neck Microvascular Free Tissue Transfer for Advanced Cutaneous Squamous Cell Carcinoma: A Comparison of Solid Organ Transplant Recipients to Nontransplant Patients

BackgroundPatients with solid organ transplant (SOT) are at increased risk of developing aggressive cutaneous malignancies due to their immunosuppression, particularly cutaneous squamous cell carcinoma PurposeThere is limited data regarding solid organ transplant patients with locally advanced cutaneous squamous cell carcinoma (cSCC) requiring radical surgery and microvascular free tissue transfer (MVFTT). Our objectives were to characterize outcomes in SOT patients and compare them with a non-SOT cohort. Study DesignThis is a retrospective cohort study of patients undergoing MVFTT for advanced cSCC of the head and neck between January 2016 and May 2020 at a tertiary referral center. Patients who underwent MVFTT as part of curative intent surgery for advanced cSCC during the study were considered for inclusion. Exclusion criteria included distant metastasis, palliative intent treatment, age less than 18 years, and lip primaries. PredictorThe predictor variable was SOT status. A cohort of non-SOT patients was matched to the SOT cohort based on age, smoking status, tumor stage, and defect size. Main outcome variablesThe primary reconstructive outcome was the major surgical complications and secondary outcome measures included major medical complications and minor surgical complications. The primary oncologic outcome was overall survival and the secondary outcome was disease-specific survival. The primary predictor was transplant status. CovariatesCovariates included patient comorbidities, prior treatment, tumor stage, type of reconstruction, pathologic findings, and adjuvant therapy. AnalysisContinuous and categorical variables were compared using Student’s T test and Fisher’s exact test. Survival was calculated using the Kaplan-Meier method and differences in survival between groups were calculated using the log-rank test. Statistical significance was set a priori at p ≤ 0.05 ResultsFourteen SOT and 14 matched non-SOT patients met inclusion criteria. There was not a statistically significant difference in the rate of major surgical complications (7% vs 7%, p = 0.74) between the SOT and non-SOT cohorts. Rates of minor (21% vs 43%, p = 0.26) wound complications and medical complications (0% vs 14%, p =0.24) were also similar between the SOT and non-SOT cohorts. Locoregional recurrences and distant metastasis were more common for SOT patients, though this was not statistically significant. Overall survival was significantly worse for SOT patients (21.7 vs 31.0 months, p = 0.04), though there was not a significant difference in disease-free survival (9.8 vs 31.0 months, p = 0.17). Conclusions and RelevanceMVFTT in the management of SOT patients with locally advanced head and neck cSCC demonstrates similar complication rates with non-SOT patients. While survival and oncologic outcomes are worse in the SOT cohort, aggressive surgical intervention with MVFTT can be performed with comparable complication rates to patients without a history of SOT.

Locally aggressive giant basal cell carcinoma of the head with focus on surgical treatment - a case report

Introduction: Basal cell carcinoma is the most common non melanoma skin cancer. It accounts for approximately 80% of all skin cancers. Case report: We presented a 62-year-old patient with a giant, deeply infiltrative, destructive lesion of the head which lasted for 15 years. Microbiological analysis showed contamination, computed tomography (CT) scan showed deep infiltration and bone destruction. The risks of operative treatment were numerous. The treatment was more complicated by infection, infiltrative spreading and the patient's comorbidity. Regardless, we decided on a wide surgical resection with pathohistological evaluation of the resection margins. The patient denied oncological treatment. After 10 years, there were no recurrent tumours. Conclusion: Aggressive surgical treatment is the treatment of choice for giant basal cell carcinoma. In the case of giant locally aggressive and advanced neoplasms, when surgery is not appropriate or not possible, medical treatment becomes oncological.

838. The Role of Surgery in the Management of Invasive Fungal Rhinosinusitis Complicated by Orbitocranial Extension in the Era of Azole Antifungals

Abstract Background Orbitocranial fungal infection (OCFI) is a potentially lethal complication of fungal rhinosinusitis, historically requiring aggressive surgery despite its significant morbidity. Over the past two decades, early use of azole agents has been introduced to support amphotericin B formulations as first-line treatment followed by step down therapy with azoles, demonstrating promising outcomes. To date, there is no data regarding the contribution of surgery in the “azole era” to patients’ survival. We aimed to provide real-life data on azole treatment outcomes and the role of surgery in the current management of OCFI. Methods Data was collected retrospectively from a chart review of the four tertiary participating centers in Israel and Australia between January 1, 2009 and January 1 2020, as well as additional cases identified through a systematic literature review (Fig. 1). The study group included patients with OCFI treated with azole antifungals. Control cases were all treated with amphotericin B. The cranial and orbital involvement was staged based on imaging (Fig. 2). The extent of surgical resection was also classified to allow for inter-group comparison. Flowchart for identification, screening, eligibility, and inclusion for the systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Staging of orbitocranial fungal infection used in the study and T1 contrast-enhanced magnetic resonance images illustrating each stage I. Orbital extent: orA - periorbit, lacrimal apparatus; orB - orbital fat; orC - oculomotor muscles; orD – optic nerve, eyeball. II. Cranial extent: crA - pterygopalatine fossa, nasopharynx; crB – temporal/infratemporal fossa; crC – cavernous sinus, dura; crD – brain, spinal cord. Results There were 125 patients in the azole anti-fungal (AAF) group and 153 in the control group (Table 1). Mucorales and Aspergillus were identified in 28% and 72% of AAF cases, respectively, and 67% and 33% of control cases, respectively (p&amp;lt; 0.001). Among patients with cranial extension, 22.6% were operated on in the AAF group and 18.4% in the control group (Table 2). However, meninges and brain resection were performed only in the controls (10.5%) and never in the azole antifungals group (p=0.045). Orbital involvement required surgery in 25.9% of AAF cases and 38.6% of controls (p=0.12). Despite a more aggressive cranial involvement, azole-treated patients’ 3-year mortality was significantly lower than controls (21% vs. 52%, HR 0.27, p&amp;lt; 0.001, Fig. 4).

Clinical Factors, Treatment Selection, and Outcomes in Postcataract Fungal Endophthalmitis from Contaminated Viscoelastics

To investigate the factors associated with treatment outcomes of postcataract surgery fungal endophthalmitis outbreaks related to contaminated viscoelastics. Retrospective analysis of clinical data from multiple institutions. This study included 228 eyes of 210 patients who were diagnosed with postcataract surgery fungal endophthalmitis related to the use of viscoelastic material (Unial, Unimed Pharmaceutical Inc); they were followed up for 6 months after the diagnosis. Clinical features and causative species were identified and treatment outcomes were analyzed in patients who underwent 6 months of follow-up. Propensity score matching was conducted to elucidate the impact of vitrectomy timing and intraocular lens (IOL) removal on treatment outcomes. Clinical factors and selection of treatment modalities associated with treatment outcomes at 6 months. Baseline visual acuity (P < 0.01), age (P= 0.05), and the presence of corneal edema (P < 0.01) were closely associated with poor best-corrected visual acuity (BCVA) at 6 months. Patients who underwent immediate vitrectomy after diagnosis showed significantly better BCVA at 6 months (mean logarithm of minimum angle of resolution 0.26 ± 0.43 vs. 0.52 ± 0.52, P= 0.03) and greater degree of visual improvement (mean-0.17 ± 0.37 improvement vs. 0.10 ± 0.57 deterioration, P= 0.03) than those who underwent deferred vitrectomy. Patients who underwent IOL removal during vitrectomy required a lower number of intravitreal antifungal agent injections (mean 8.9 ± 9.1 vs. 16.7 ± 12.2, P < 0.01) and showed a lower incidence of repeated vitrectomy (20% vs. 82%, P<0.01) than in those without IOL removal. In postcataract fungal endophthalmitis, prompt vitrectomy at the time of diagnosis resulted in better treatment outcomes, and IOL removal reduced the treatment burden. Prompt and aggressive surgicalintervention should be considered for postcataract fungal endophthalmitis.

A Rare Case of Cecostomy Tube in Complicated Acute Appendicitis Leading to Fecal Peritonitis

The most common abdominal surgical emergency in the world in acute appendicitis. Most common age group involved is between first to second decades but patients at extreme age have higher mortality rate due to late presentation. We are presenting a case of appendicitis which was complicated as long history at time of first surgery which led to caecal injury which was managed with ceacostomy. 62 years gentleman was referred from private hospital with fecal discharge from the open appendectomy wound and cecostomy tube insitu. Patient was diagnosed as phlegmon sequelae of acute appendicitis. Patient underwent emergency laparotomy, peritoneal lavage, removal of cecostomy tube, primary repair of caecal perforation and diversion loop ileostomy. Patient recuperated well. This case report highlights the challenges faced and complexities associated with failure of cecostomy in managing caecal perforation following laparoscopic appendectomy. The conversion from a laparoscopic approach to an emergency open appendectomy followed with cecostomy proved to be a vital decision in the face of phlegmon sequelae of acute appendicitis. The phlegmonous nature of acute appendicitis should be managed conservatively otherwise leading to a more aggressive surgical intervention.
