Ruptured pancreatic carcinosarcoma - A case of extended survival following surgical resection and chemotherapy.

We present a rare case of ruptured pancreatic carcinosarcoma in a 56-year-old male who underwent radical surgery and adjuvant chemotherapy. Despite the typical poor prognosis associated with this aggressive tumor, the patient achieved an overall survival of 20 months postoperatively. This case emphasizes the challenges in diagnosing and managing pancreatic carcinosarcoma and highlights the potential benefits of aggressive surgical and chemotherapeutic interventions in achieving extended survival.

The Role of Coronoidectomy in Complex Mandibular Reconstruction With Free Fibular Flap

Introduction: Complex mandibular reconstruction is at risk of postoperative restricted mouth opening. Temporomandibular joint pseudoankylosis can cause significant disability, leading to restricted mouth opening and an inability to create a proper seal with the mouth. Treating this condition often requires aggressive surgical intervention, primarily restoring the structure and functionality of the mandible. Coronoidectomy plays a vital role in improving mouth opening capacity. Case Presentation: Four patients with temporomandibular joint pseudoankylosis were included in this case series. The patients reported being unable to move their remaining lower jaw, having a perpetually open mouth, and constant drooling. All patients had a history of reconstructive surgery due to tumor or malignancy and could only open the mouth less than 10 mm. They underwent coronoidectomy followed by free fibular flap reconstruction. Postoperatively, all 4 patients exhibited a movable mandible and achieved proper occlusion. The maximum mouth opening increased by 25 to 45 mm; all flaps appeared vital, sutures remained intact, and no active bleeding. Discussion: Coronoidectomy is crucial for enhancing the ability to open the mouth. All of the patients underwent a coronoidectomy surgery followed by free fibular flap reconstruction. Immediately after the surgery, the mandibular projection appears nearly symmetrical, the patient opens their mouth, and occlusion is achieved subjectively. From our presented cases, after coronoidectomy, all patients had movable mandibula, and mouth opening was achieved. Coronoid process resection frees the mandible from the temporalis. Coronoidectomy and separation of the temporalis muscle from the mandible have excellent clinical efficacy for improving mouth opening and movement. Conclusion: Coronoidectomy followed by a free fibular flap should be considered the best surgical option for patients with restricted mouth opening after complex mandibular reconstruction.

OSTEONECROSE DOS MAXILARES INDUZIDA PELO USO DE MEDICAMENTOS

The study details the etiology of the disease, associated medications, risk factors, clinical characteristics and diagnosis, in addition to prevention and treatment strategies. MAOM occurs mainly in patients using these medications to treat conditions such as osteoporosis and cancer, due to the inhibition of bone remodeling and angiogenesis. It explores the lack of consensus in the literature on the diagnosis and treatment of AOM, emphasizing the importance of dental surgeons’ knowledge of the medications involved and appropriate management. The work reviews the scientific literature on the topic and proposes that prevention, including a detailed dental evaluation before starting treatment with these medications, is crucial to reducing the risks of osteonecrosis. Treatment, in turn, ranges from conservative approaches with the use of antibiotics and strict oral hygiene to more aggressive surgical interventions, depending on the stage of the disease. Photodynamic therapy is mentioned as a promising auxiliary technique for treatment. In its final considerations, the study highlights the need for early diagnosis and rigorous preventive approaches to avoid severe complications.

Malnutrition in patients with obesity: An overview perspective.

Malnutrition in patients with obesity presents a complex and often overlooked clinical challenge. Although obesity is traditionally associated with overnutrition and excessive caloric intake, it can also coincide with varying degrees of malnutrition. The etiopathogenesis of obesity is multifaceted and may arise from several factors such as poor diet quality, nutrient deficiencies despite excess calorie consumption, genetics, and metabolic abnormalities affecting nutrient absorption and utilization. Moreover, a chronic low-grade inflammatory state resulting from excess adipose tissue, commonly observed in obesity, can further exacerbate malnutrition by altering nutrient metabolism and increasing metabolic demands. The dual burden of obesity and malnutrition poses significant risks, including immune dysfunction, delayed wound healing, anemia, metabolic disturbances, and deficiencies in micronutrients such as vitamin D, iron, magnesium, and zinc, among others. Malnutrition is often neglected or not given enough attention in individuals with obesity undergoing rapid weight loss through aggressive caloric restriction, pharmacological therapies, and/or surgical interventions. These factors often exacerbate vulnerability to nutrition deficiencies. We advocate for healthcare practitioners to prioritize nutrition assessment and initiate medical intervention strategies tailored to address both excessive caloric intake and insufficient consumption of essential nutrients. Raising awareness among healthcare professionals and the general population about the critical role of adequate nutrition in caring for patients with obesity is vital for mitigating the adverse health effects associated with malnutrition in this population.

Locally Advanced Splenic Flexure Tumor With Invasion And Formation Of Splenic Abscess

Introduction: Splenic abscesses are rare, with an incidence of 0.14-0.70% in autopsies, affecting mainly men and immunosuppressed patients. Symptoms include fever, abdominal pain, nausea, and vomiting. Splenic invasion by colon cancer at the splenic flexure is uncommon. We report a case of cancer at the splenic flexure resulting in a splenocolic fistula and splenic abscess. Case Description: A 43-year-old man, with a history of injectable drug use, presented with diffuse abdominal pain. Tests revealed leukocytosis, thrombocytopenia, and elevated bilirubins and liver enzymes. A CT scan identified thickening in the colon and a splenic abscess. Total splenectomy and left colectomy with colon-colonic anastomosis were performed. Discussion: Splenic abscesses are rare and, when associated with colonic neoplasms, present a diagnostic and therapeutic challenge. This case highlights the importance of aggressive surgical intervention to treat tumor invasions and associated complications.

7799 Nesidioblastosis Concurrent with Anatomically Confirmed Metastatic Gastric Cancer

Abstract Disclosure: Y. Cho: None. K. Jo: None. J. Han: None. S. Moon: None. E. Kim: None. Background: Nesidioblastosis is a rare condition that should be considered in cases of pancreatogenic hyperinsulinemic hypoglycemia without evidence of insulinoma on imaging. We present the first case of nesidioblastosis concomitant with anatomically confirmed metastatic gastric cancer of the pancreas. Case Report A 57-year-old male presented with recurrent episodes of loss of consciousness and hypoglycemia, with a glucose level of 26 mg/dl upon arrival at the emergency room. Despite a history of advanced gastric cancer and previous chemotherapy, the patient had not been diagnosed with diabetes and was not taking medications associated with hypoglycemia. Four months prior, he underwent total gastrectomy. The fasting plasma glucose levels was 38 mg/dl, accompanied by C-peptide levels of 6.10 ng/mL, insulin levels exceeding 1000 uIU/ml, and proinsulin levels at 8.8 pmol/L. The insulin antibody level was more than 100%, and the highest cortisol level reached 15.60 ug/dL during the rapid ACTH stimulation test. The patient's postprandial 2-hour glucose level reached 233 mg/dl during the 75g glucose tolerance test. Imaging studies, including whole-body PET CT and abdominal CT, showed no evidence of suspected metastatic lesions, and the pancreas appeared normal on MRI. Endoscopic ultrasound could not be performed due to anatomical changes following the surgery. A selective arterial calcium stimulation test demonstrated a substantial over twofold increase in insulin concentrations in the gastroduodenal artery, splenic artery, and superior mesenteric artery. The patient received methylprednisolone 125 mg once daily but insulin levels remained elevated, exceeding 1000 uIU/ml, requiring continuous dextrose infusion. Octreotide therapy was initiated, resulting in an improvement in insulin levels to 589 uIU/ml, although discontinuation of dextrose fluid remained unfeasible. After consultation with the surgeon, a open subtotal pancreatectomy was performed, allowing discontinuation of dextrose on the second post-surgery day, with improved glucose and insulin levels. Histological examination showed three clusters of atypical cells with perineural infiltration. Immunostaining indicated negative synaptophysin and positive CK20, suggesting possible gastric cancer metastasis, consistent with prior gastrectomy findings. Moreover, an increased number of variable-sized Langerhans islets exhibited positive insulin and glucagon immunostaining within the islets, indicative of nesidioblastosis. Conclusion: Nesidioblastosis should be considered in cases of unexplained post-surgery hypoglycemia following metastatic gastric cancer treatment. Furthermore, given the potential link with metastatic gastric cancer, which may elude detection via imaging alone, aggressive surgical intervention should be contemplated as a nesidioblastosis treatment strategy.

Role of Necrosectomy in Necrotizing Pancreatitis: A Narrative Review.

Necrotizing pancreatitis (NP) is a severe complication of acute pancreatitis, characterized by necrosis of pancreatic and peripancreatic tissues, leading to significant morbidity and mortality. The role of necrosectomy, the surgical removal of necrotic tissue, in the management of NP has evolved over the past few decades, moving from early aggressive surgical intervention to a more conservative and stepwise approach. This narrative review explores the historical perspectives, current practices, and future trends in the role of necrosectomy in NP. Early studies favored open surgical debridement; however, high mortality rates associated with early intervention prompted a shift towards minimally invasive techniques, delayed interventions, and the "step-up approach,"combining percutaneous drainage with minimally invasive surgery. We also review the indications for surgery, optimal timing, and various techniques, including video-assisted retroperitoneal debridement and endoscopic transluminal necrosectomy. The review highlights the benefits of these strategies in reducing complications, improving patient outcomes, and minimizing hospital stays. Ongoing research into patient selection, timing, and procedural refinement will continue to shape the role of necrosectomy in NP management. Understanding the evolving role of necrosectomy is crucial for optimizing care and reducing the burden of this life-threatening condition.

Management and Long-Term Outcomes of Patients With Hepatic Epithelioid Hemangioendothelioma.

Hepatic epithelioid hemangioendothelioma (HEHE) is an uncommon vascular neoplasm characterized by variable clinical behavior. Our aim was to describe the therapeutic approach for HEHE at diagnosis and define clinicopathological characteristics associated with tumor progression and long-term survival. This is a retrospective study that includes patients with HEHE who received treatment at Mayo Clinic Rochester between 1984 and 2023. Eighty patients were included in the study (median age: 44 years; 62.5% female), 24 underwent liver transplantation, 26 underwent liver resection, and 30 were managed medically. The 3-year overall survival rates were 86.7%, 80.9%, and 51.1%, respectively. Notably, 26 patients had extrahepatic metastases at the time of diagnosis, four (16.7%) in the transplantation group, four (15.4%) in the resection group, and 18 (69.2%) in the nonsurgical group. On multivariable modeling, bone metastasis was independently associated with long-term mortality (HR 6.3, p < 0.001) while lung metastasis and surgical intervention were not associated with long-term mortality (HR 0.8, p = 0.8; HR 1.1, p = 0.9, respectively). Bone metastasis emerged as a strong predictor of poor survival. Hence, aggressive surgical intervention may not be advantageous in patients with skeletal metastases but can still be offered for those with other extrahepatic metastases.

Evaluating Treatment Modalities for Reducing Recurrence in Central Giant Cell Granuloma: A Narrative Review.

Treating central giant cell granuloma (CGCG) is challenging due to high recurrence rates and variable therapy responses. This study examines the efficacy of various treatments in reducing CGCG recurrence. A literature review explored outcomes of surgical excision, curettage, intralesional corticosteroid injection, and adjuvant therapy, considering factors like lesion location, size, and histological features. Aggressive surgical techniques such as en bloc resection were found to potentially lower recurrence rates compared to conservative approaches. However, treatment should be tailored to individual patient needs. Further research is needed to confirm these findings and improve treatment strategies. A concise literature review was conducted using PubMed, MEDLINE, and Google Scholar, focusing on papers published from 1986 to 2024. Search terms included "central giant cell granuloma", "recurrence", "treatment modalities", and "surgical excision". Studies reporting recurrence rates and treatment outcomes for CGCG were analyzed. Twenty-nine studies were reviewed, including six studies on surgical excision and curettage, eight studies on intralesional corticosteroid injections, six studies on calcitonin therapy, five studies on interferon-alpha therapy, and four studies on the therapy with denosumab. Analysis indicated that aggressive surgical treatments like en bloc resection were associated with lower recurrence rates compared to conservative methods. Predictors of recurrence included lesion size (>3 cm), location (mandible), and aggressive histopathological features. Aggressive surgical excision combined with nonsurgical methods may lower recurrence rates, while conservative techniques remain viable in some cases. Further prospective research is needed to validate these findings and enhance CGCG treatment options.

Inherited Basaloid Neoplasms Associated With SUFU Pathogenic Variants.

Germline SUFU pathogenic variants (PVs) have previously been associated with basal cell nevus syndrome (BCNS) and multiple infundibulocystic basal cell carcinoma syndrome; however, a broader spectrum of cutaneous findings in patients with SUFU PVs has not been well delineated. To define the clinical and histopathologic spectrum of cutaneous findings in patients with germline SUFU PVs. This case series was conducted in multiple US academic dermatology, medical genetics, and medical oncology clinics between July 2014 and July 2022. The study included patients with confirmed germline SUFU PVs who were evaluated by a dermatologist. The analysis took place from March to September 2023. Histopathologic evaluation of skin biopsies with or without immunohistochemical staining, and targeted next-generation sequencing (NGS) on tumor specimens. All 5 patients were women. The mean (range) age at presentation was 50.2 (31-68) years, with skin manifestations initially appearing in the fourth to sixth decades of life. None had keratocystic odontogenic tumors. A total of 29 skin pathology specimens from the 5 patients were reviewed; of these, 3 (10.3%) were diagnosed as basaloid follicular hamartomas (BFHs), 10 (34.5%) classified as infundibulocystic basal cell carcinomas (iBCCs), 6 (20.7%) classified as nodular basal cell carcinomas (nBCCs), and 1 (3.4%) as infiltrative basal cell carcinoma (BCC). Targeted NGS studies on tumor specimens suggest that an increased number of UV-signature variants is associated with basal cell carcinomas compared with more indolent basaloid follicular hamartomas. Patients with germline SUFU PVs may present with multiple indolent basaloid neoplasms in addition to conventional basal cell carcinomas, typically appearing in the fourth to sixth decades of life. Although there are overlapping clinical manifestations, these findings help to differentiate the clinical syndrome associated with SUFU PVs from PTCH1 BCNS. Awareness of the clinicopathologic spectrum of SUFU-associated basaloid neoplasms is important for dermatologists and dermatopathologists because many (although not all) of these lesions are indolent and do not require aggressive surgical treatment. Importantly, because SUFU lies downstream of the protein smoothened, vismodegib and other smoothened inhibitors are unlikely to be effective therapies in this subset of patients.

Evolution of Medical and Surgical Management of Carotid Disease from Carotid Endarterectomy to Transfemoral Carotid Stenting to TCAR

Patients with carotid stenosis can be broadly classified into two categories: symptomatic and asymptomatic. While there is little disagreement about surgical management of symptomatic carotid stenosis, the optimal management strategy for the patients with asymptomatic carotid disease has undergone significant evolution over past five decades. With increasing focus on role of plaque morphology on the etiology of symptoms, there has been an increased focus on optimizing the medical management targeted at plaque stabilization, especially for the patients with asymptomatic carotid disease, while reserving the most aggressive surgical treatment options for the patients with symptomatic carotid stenosis. This review summarizes the scientific evidence based on multiple large clinical studies showing how the modern-day management of carotid stenosis has evolved. Multiple, large randomized clinical trials have established carotid endarterectomy (CEA) as the treatment of choice for symptomatic patients with symptomatic, >50% stenosis of carotid artery or those who have asymptomatic high grade carotid stenosis. With the advancements in endovascular techniques, the technique of Trans Femoral Carotid Artery Stenting (TF-CAS) was popularized, but after multiple, large randomized controlled trials demonstrated superiority of CEA, the indications for TF-CAS as the initial operation of choice for carotid disease for all patients have been reduced. In the past five years, the introduction of the newer technique of Trans Carotid Artery Revascularization (TCAR) has shown promising results with significant reduction in the incidence of perioperative complications as compared to CEA and TF-CAS, however, there have been no randomized controlled trials comparing TCAR to either CEA or TF-CAS. Moreover, with the developments in the medical field with introduction of several new medications which have been demonstrated to successfully change the plaque morphology, there has been a renewed interest in exploring if the indications for surgical management for the asymptomatic carotid disease should be revisited.

The Clinicopathological Features and Prognoses of Lower Uterine Segment Cancer: A Retrospective, Single-Center Cohort Study.

This study used single-center data to analyze the clinicopathological features of site-specific endometrial cancer. Patients with endometrial carcinoma who had undergone surgery at Peking Union Medical College Hospital, China, between March 2016 and January 2022 were enrolled. Clinical information and pathological characteristics were summarized, and microsatellite status was analyzed using the immunohistochemical method. Patient prognoses were measured in terms of the rates of overall survival and progression-free survival. The mean patient age was 49 years (ranging: from 25 to 76 years old), and there was no difference in clinicopathological features between endometrioid and type II endometrial carcinoma in LUSC. The ER and PR expression ratios were 80.4% and 64.3%, respectively, in this LUSC cohort, and the MMR deficiency ratio was 33.9%, including 39.6% in endometrioid carcinoma and 15.4% in type II endometrial carcinoma. Combined MSH2&MSH6 loss was more common than combined MLH1&PMS2 being unexpressed (16.1% vs 12.5%), and dMMR patients differed significantly from the pMMR group in terms of vascular invasion (P=0.003). The combination of chemotherapy and radiotherapy did not provide a statistically significant improvement in prognosis compared to chemotherapy alone. The results of this study showed that LUSC patients tended to be younger and their tumors had less expression of hormone markers. The biological behavior of both endometrioid cancer and type II EC may be similar when EC occurs in this area. Furthermore, this type of tumor also showed a higher incidence of vascular invasion, and the combination of chemotherapy and radiotherapy did not provide significant improvement. Thus, successful treatment of LUSC tumors requires aggressive surgical intervention and a more effective postoperative treatment approach.

ROTATIONAL AND ANGULAR MALALIGNMENT FOLLOWING TITANIUM ELASTIC NAILING SYSTEM AND HIP SPICA CAST FOR FEMUR DIAPHYSEAL FRACTURES IN FOUR- TO SIX-YEAR-OLD CHILDREN: A RANDOMIZED PROSPECTIVE STUDY

Femoral shaft fractures are fairly common injuries in paediatric age group. The treatment protocols are clear in patients of age less than 4 years and greater than 6 years. The real dilemma lies in the age group of 4–6 years. The aim of this study is to find whether a conservative line should be followed, or a more aggressive surgical intervention can provide significantly better results in these injuries.This study was conducted in a tertiary care hospital in Bhubaneswar, India from January 2020 to March 2021. A total of 40 patients with femur shaft fractures were included and randomly divided in two treatment groups. Group A were treated with a TENS nail while group B were treated with skin traction followed by spica cast. They were regularly followed up with clinical and radiological examination to look out for signs of healing and any complications. TENS was removed at 4–9 months’ time in all Group A patients.Group A patients had a statistically significant less hospital stay, immobilisation period, time to full weight bearing and radiological union. Rotational malunions were significantly lower in Group A (p-value 0.0379) while there was no statistically significant difference in angular malunion in coronal and sagittal plane at final follow up. Complications unique to group A were skin necrosis and infection.We conclude that TENS is better modality for treatment of shaft of femur fractures in patients of 4–6 years age as they significantly reduce the hospital stay, immobilization period and rotational malalignment.

Analysis of Expression of the ANG1, CaSR and FAK Proteins in Uterine Fibroids.

Understanding the molecular factors involved in the development of uterine myomas may result in the use of pharmacological drugs instead of aggressive surgical treatment. ANG1, CaSR, and FAK were examined in myoma and peripheral tissue samples taken from women after myoma surgery and in normal uterine muscle tissue samples taken from the control group. Tests were performed using tissue microarray immunohistochemistry. No statistically significant differences in ANG1 expression between the tissue of the myoma, the periphery, and the normal uterine muscle tissue of the control group were recorded. The CaSR value was reduced in the myoma and peripheral tissue and normal in the group of women without myomas. FAK expression was also lower in the myoma and periphery compared to the healthy uterine myometrium. Calcium supplementation could have an effect on stopping the growth of myomas.

Clinical Outcomes After Definitive Treatment of Soft Tissue Sarcoma of the Hand: A Retrospective Cohort Study of 109 Patients

The purpose of this study was to provide updated data on oncologic outcomes following definitive surgical treatment of soft tissue sarcoma of the hand in a cohort of 109 patients, as well as to characterize risk factors for poor oncologic and functional outcomes. We analyzed data from 109 consecutive patients who had definitive surgical treatment for soft tissue sarcoma of the hand performed between 1996 and 2019 by a single surgeon at a sarcoma center. Primary outcomes included functional outcome (assessed by Musculoskeletal Tumor Society scores), disease-free survival (DFS), and overall survival (OS). We compiled descriptive data and used a multivariable linear model to identify factors associated with functional outcomes. Kaplan-Meier methods were used to estimate 5- and 10-year DFS and OS. Patients had a median age of 36 years at presentation. Median follow-up was 6.1 years among patients alive at the end of follow-up. The median Musculoskeletal Tumor Society score was 29; functional outcome was worse among patients with high-grade tumors or complications. Among the 107 patients who became disease-free, there were four local recurrences (one with metastasis), six distant recurrences, and one death without recurrence. All local recurrences were deep tumors (two myxofibrosarcoma and two myxoinflammatory fibrosarcoma). Estimated 5- and 10-year DFS rates were 89% (95% confidence interval [CI]: 83% to 96%) and 88% (95% CI: 80% to 95%). There were seven deaths, and the estimated 5- and 10-year OS rates were 95% (95% CI: 90% to 100%) and 92% (95% CI: 84% to 100%). Larger tumor size and higher stage at diagnosis were associated with shorter DFS and OS in univariable analyses; low event rates precluded multivariable analysis of survival. Aggressive disease-specific surgical and multidisciplinary treatment can yield long DFS and OS, and good functional outcomes. However, complications and high-grade tumors are associated with worse functional scores. Prognostic II.

Surgical treatment of appendiceal mucormycosis in an immunocompromised patient: a case report

BackgroundGastrointestinal mucormycosis is a rapidly progressing and often fatal disease, predominantly affecting immunocompromised patients. Surgical intervention, in addition to antifungal therapy, is essential. Herein, we describe the successful management of appendiceal mucormycosis in a patient with acute promyelocytic leukemia through rapid surgical intervention and antifungal therapy.Case presentationA 29-year-old woman underwent autologous peripheral blood stem cell transplantation for acute promyelocytic leukemia (APL). Subsequently, her condition relapsed, and remission induction therapy was initiated. During the immunosuppressive period, she developed a fever and severe abdominal pain. Computed tomography revealed severe edema of the ileum, cecum, and ascending colon. Despite receiving multiple antibiotics, antivirals, and antifungals, her condition showed no improvement. Consequently, she underwent exploratory laparotomy, with no bowel perforation noted, revealing severe inflammation in the ileum, cecum, and ascending colon, as well as appendiceal necrosis. Appendectomy was performed, and histopathological analysis revealed hyphae in the vessels and layers of the appendiceal wall, suggestive of mucormycosis. The patient was diagnosed with appendiceal mucormycosis, and liposomal amphotericin B was administered. Subsequent monitoring showed no recurrence of mucormycosis. Genetic analysis of the resected tissue revealed Rhizopus microspores as the causative agent.ConclusionsRapid surgical intervention and antifungal drug administration proved successful in managing appendiceal mucormycosis in a patient with APL. Early recognition and aggressive surgical intervention are imperative to improve outcomes in such patients.

Invasive Fungal Sinusitis and Its Orbital Morbidity in Pediatric Population: A Strategic Treatment Algorithm and Outcomes.

Invasive fungal sinusitis, particularly mucormycosis, presents a significant clinical challenge, especially in pediatric populations. This retrospective epidemiologic study aimed to investigate the clinical characteristics, risk factors and outcomes associated with this rare but severe condition, with a focus on orbital morbidity. Clinical data of 12 pediatric patients diagnosed with invasive fungal sinusitis between 2021 and 2023 were retrospectively analyzed. Diagnosis involved microbiological and histopathologic examinations, alongside radiologic imaging. Treatment comprised surgical intervention and antifungal therapy, with a detailed evaluation of orbital involvement. Statistical analysis included descriptive statistics and logistic regression. Predominantly affecting males, the median age of the patients was 8 years. Common symptoms included orbital swelling and impaired vision. Imaging revealed characteristic features of invasive fungal sinusitis, including fat stranding and bone erosions. Orbital involvement was extensive, with poor visual outcomes observed in several cases. Surgical debridement and antifungal therapy, including transcutaneous retrobulbar Amphotericin B, were administered. Risk factors associated with poor orbital outcomes included duration of diabetes and glycated hemoglobin levels. Mortality rate stood at 22.2%. Early diagnosis, aggressive surgical intervention and combined antifungal therapy are essential for improving outcomes. Timely intervention showed stabilization of the orbital disease and better outcomes in pediatric patients. Further research with larger sample sizes is warranted to better understand and address this serious condition.

A Study on the Involvement of Facial Bones in Mucormycosis Patients.

To study the involvement of various facial bones in mucormycosis patients. 50 Mucormycosis patients were included in the study after getting their consent from a tertiary care center in Chennai. 50 mucormycosis patients were included from a tertiary care centre in Tamilnadu.The details regarding their symptoms-onset, duration and progression, associated comorbidities were noted.The involvement of various facial bones were assessed by CT paranasal sinuses/CT facial bones and MRI brain with orbit with contrast. Among the study population, the nasal cavity and maxillary sinuses were affected first. In patients who are presenting late, this infection spreads to the base of skull through blood vessels and presents as rhino-orbito-cerebral form.Patients presenting late had high chances of bony erosion.Maxillary osteomyelitis and necrosis has been observed commonly.22 patients had facial bone involvement in this study and they needed thorough wound debridement with removal of the necrosed bone. Mucormycosis is often accompanied by a poor prognosis and a high mortality rate. Hence, aggressive surgical intervention with antifungal therapy is usually necessary. Early diagnosis and prompt treatment can reduce the mortality and morbidity of this lethal fungal infection.

Ultrasound biomicroscopic imaging parameters associated with outcome in equine infectious ulcerative keratitis and stromal abscesses.

To determine the predictive value of corneal ultrasound biomicroscopy (UBM) findings for the outcome of equine corneal disease. 46 horses with a clinical diagnosis of either infectious ulcerative keratitis or stromal abscess. Corneal UBM (VevoMD; UHF70; VisualSonics) of horses with infectious corneal disease presenting to the North Carolina State University Equine Ophthalmology Service from 2019 to 2023 were evaluated. Size and depth of lesion, presence of Descemet membrane disruption (DMD), corneal thickness, and aqueous humor cell counts (AHCC) were assessed. Comparisons of UBM and clinical exam findings, presence of infectious organisms, and outcome (healed or enucleated) were performed. The UBMs from 46 horses were evaluated. Increased AHCC was significantly associated with increased size and depth of corneal lesions on UBM but not with DMD. Deep lesions and DMD were significantly associated with an enucleation outcome. Horses treated with systemic antibiotics had significantly lower AHCC on UBM, but there were no differences in AHCC with the use of other systemic or topical medications. There was no significant correlation between infectious disease results, clinical findings (aqueous flare or cells), outcome, and UBM AHCC. Parameters on UBM, such as depth of lesion, DMD, and AHCC, may be useful diagnostic and prognostic tools to augment the ophthalmic exam of horses with corneal disease. The UBM findings of deep corneal lesions and DMD suggest a poor prognosis and warrant aggressive surgical intervention.

Management of Neonatal Hepatic Hemangiomas: A Single-Center Experience Focused on Challenging Cases.

Background: Management of hepatic hemangioma (HH) in infancy ranges from close monitoring to surgical resection. We analyzed the clinical characteristics and outcomes of HH according to its treatment options, with particular focus on challenging cases. Methods: Data of patients diagnosed with HHs in their first year of life and followed up for at least 1 year were retrospectively reviewed and divided into treatment and observation groups. Serial imaging results, serum alpha-fetoprotein (AFP) levels, medications, and clinical outcomes were compared. The detailed clinical progress in the treatment group was reviewed separately. Results: A total of 87 patients (75 in the observation group and 12 in the treatment group) were included. The median HH size at the initial diagnosis and the maximum size were significantly larger in the treatment group than the observation group (2.2 [0.5-10.3] cm vs. 1.0 [0.4-4.0] cm and 2.1 [0.7-13.2] vs. 1.1 [0.4-4.0], respectively; all p < 0.05]. The median initial and last serum AFP levels were significantly higher in the treatment group than in the observation group (76,818.7 vs. 627.2 and 98.4 vs. 8.7, respectively; all p < 0.05). Serum AFP levels in both groups rapidly declined during the first 3 months of life and were almost undetectable after 6 months. Among the challenging cases, a large (14 × 10 × 6.5 cm sized) focal HH was successfully treated using stepwise medical-to-surgical treatment. Conclusions: Patients with large HH and mild symptoms can be treated using stepwise pharmacotherapy. More aggressive surgical treatment of tumors unresponsive to initial pharmacotherapy may help shorten the treatment period and improve outcomes.
