Health profiling of conscripts from the Orenburg region drafted to serve in the Armed Forces of Russia

Relevance. Amid international unrest, Russia’s top priority is to augment its defense capacities. The President of Russia decided to increase the army and navy corps by 30 %. To fulfill this task, physically strong and healthy conscripts are required to man the military units.The objective is to analyze medical examination data of drafted young men aged 17 to assess the health profile of conscripts from the Orenburg region.Methods. The study relied on Rosstat statistics for the Orenburg region, as well as reports and records of the Military Medical Expertise Center at the Federal Budgetary Institution “Military Commissariat of the Orenburg Region” collected over a decade’s timespan from 2014 to 2023. Conscripts were split into the following categories labelled by letters of the Russian alphabet: ‘A’ for fit for military service, ‘B’ for fit for military service with minor restrictions, ‘V’ for fit for military service with limitations, ‘G’ for temporarily unfit for military service, ‘D’ for unfit for military service. In addition, conjoined analysis of A & B categories of conscripts fit for military service vs V & D ‘unfit or fit for military service with limitations’ was performed for peace-time settings. The incidence of diseases in conscripts was correlated with relevant chapters of the International Classification of Diseases and Behavioral Disorders (ICD-10); calculations per 1000 conscripts (‰) were carried out. The obtained dynamics across different indicators was studied using dynamic series analysis and second-order polynomial trend; the determination coefficient was calculated as well.Results and discussion. Within the last decade, the number of conscripts in the Orenburg region has not shown any sig nificant dynamics and is likely to remain unchanged in the coming years. The results showed that every 1,000 of examined conscripts included 761 those who were fit for military service, 98 needed treatment or rehabilitation, and 141 were unfit or fit with limitations. The annual disease incidence rate among B & D category conscripts was (141.6 ± 2.6) ‰, standing for 14.1% of all the examined conscripts. In terms of significance, rank 1 was assigned to musculoskeletal and connective tissue (ICD-10, Chapter XIII), rank 2 to mental and behavioral disorders (Chapter V), rank 3 to circulatory diseases (Chapter IX), rank 4 to diseases of the eye and adnexa (Chapter VII), rank 5 to nervous system disorders (Chapter VI). Among all military service exemption causes in conscripts, cumulative specific contribution of these diseases was 61.9%. In 2014-2023, the average of 8.3% of conscripts needed conservative treatment, with treatment provided to 87.1% of those in need of treatment; 1.5% needed surgical treatment (treatment received by 79.4%) and 48.3% needed oral cavity sanitation (79.4% treated accordingly). Conscripts with eye-sight disorders underwent vision correction.Conclusion. Follow-up observation, medical and healthcare initiatives, and extensive promotion of healthy lifestyles allowed to improve the conscripts’ health status. The undertaken measures increased in the overall fitness for military service, allowing to sustainably deliver on Russia’s conscription demands.

Larger than life: A case of a bleeding giant phyllodes tumor in a COVID-19 positive patient

Introduction: Phyllodes tumor of the breast, also known as cystosarcoma phyllodes, is a rare fibroepithelial tumor that accounts for about 0.3–1% of all breast tumors. Unlike most breast tumors that start from the ducts and gland, phyllodes tumor originates from the stroma. The classification of phyllodes tumor is less important on assessing the risk of recurrence as compared to the presence of tumor-free margins after surgical treatment. Case Report: A 54-year-old female presented at the emergency room with a large, bleeding, left breast mass. The patient tested positive for COVID-19 and was admitted previously at the isolation ward. After medical management of her current condition, the patient underwent wide excision (total mastectomy), left with en bloc resection of pectoralis major with delayed reconstruction via split thickness skin graft. This case is one of the few reported giant phyllodes tumor in the English literature, measuring 30 cm widest dimension. Conclusion: Malignant phyllodes tumor is a rare form of breast malignancy behaving like a sarcoma. A diagnostic dilemma may be encountered in patients with such tumors due to the rarity of these cases and the different presentation of the tumor. High suspicion shall be entertained for patients with breast masses which tend to appear like benign lesions but with sudden enlargement. Adequate surgical intervention shall be done ensuring tumor-free margins. Adjuvant therapy for malignant phyllodes tumor is still controversial but shall be entertained according to the patient’s actual case needs.

Hotspots and future trends of dermatofibrosarcoma protuberans

ObjectiveDermatofibrosarcoma protuberans (DFSP) is a moderately malignant soft tissue sarcoma with localized infiltrative growth. The extensive surgical scope and high recurrence rate of DFSP brings dysfunctional, aesthetic, psychological and economic problems to patients. The aim of this study is to explore the global publication characteristics, research hotspots and future trends of DFSP over the past 32 years via an intuitive visualized way.MethodsThe Web of Science Core Collection (WoSCC) database was searched for papers related to DFSP published from 1990 to 2022. Then bibliometric analysis of these publications was performed, including collaborative networks, co-citation analysis of journals and references, and cluster analysis of keywords.ResultsA total of 1588 papers were retrieved between 1990-2022. The United States was the most prolific country, followed by China. The article Imatinib Mesylate in Advanced Dermatofibrosarcoma Protuberans: Pooled Analysis of Two Phase II Clinical Trials, received most citations. Research hotspots and future trends are mainly focused on disease diagnosis, COL1A1-PDGFB fusion gene, drug and surgical treatment, fibrosarcomatous transformation, and immunotherapy.ConclusionThe research on DFSP faces several clinical challenges. This study provides novel insights into future research directions and scientific decisions for DFSP.

Clinical Outcome and Quality of Life after Modular Reverse Total Shoulder Arthroplasty in Comparison with Joint‐Preserving Locking Plate Osteosynthesis in Aged Patients: A Retrospective Comparison Study

ObjectivesProximal humeral fractures (PHFs) show a high incidence in aged patients. While nondisplaced fractures achieve good results by conservative treatment, surgical procedures are discussed controversially. Next to open reduction and internal fixation (ORIF), the primary use of reverse shoulder arthroplasty (RSA) has become increasingly important. The aim of this study was to investigate the clinical function, activities of daily living (ADL), as well as pain assessment in patients with PHFs, treated by ORIF or RSA.MethodsA retrospective comparison study was assessed. From November 2011 to March 2016, 34 patients (17 matched pairs) that had undergone either ORIF or RSA of the proximal humerus, were included in this study. Pain was measured by numeric rating scale (NRS). ADL were obtained by Katz‐Index and SF‐12. Moreover, shoulder function was assessed using the Oxford Shoulder Score (OSS). The maximum range of motion (ROM) was also recorded. From November 2011 to March 2016, 34 patients (17 matched pairs) that had undergone either ORIF (Figure or RSA of the proximal humerus) were included in this study. For statistical analyses, Student's t‐test, Wilcoxon test, and Chi‐Quadrat test were used. Statistical significance was indicated with p < 0.05.ResultsTotally 34 patients with an average age of 76.6 years were included. Surgical treatment was performed on average 5.2 days after diagnosis, differing significantly between the two groups (RSA/ORIF: 6.9/3.5 days) The operation time of RSA (97 min) was significantly longer than for ORIF (78 min). Pain assessment, as well as the Katz‐Index and the SF‐12, showed no significant differences. Moreover, clinical shoulder function showed no significant discrepancies between the two surgical techniques.ConclusionsAged patients with PHFs treated with RSA display similar results regarding clinical function, ADL as well as pain perception compared with ORIF. However, revision surgery rate was lower in patients who underwent RSA. Thus, the surgical treatment of PHFs by RSA represents an excellent alternative, especially with regard to an aging patient population.

Abstract 4134712: Pheochromocytoma-Induced Cardiomyopathy Requiring Mechanical Support with Ejection Fracture Recovery Following Surgical Resection

Introduction: Pheochromocytomas are catecholamine-secreting tumors that arise from chromaffin cells of the adrenal medulla. The annual incidence is approximately 0.8 per 100,000 persons, though this is an underestimate given a high percentage diagnosed at autopsy. Classically, patients present with episodic headache, sweating, and tachycardia, however, pheochromocytomas can be associated with cardiomyopathy secondary to the catecholamine excess. We present an unusual case of pheochromocytoma-induced cardiogenic shock highlighting an excellent use of mechanical circulatory support with Impella and Extracorporeal Membrane Oxygenation (ECMO) bridging to surgical intervention resulting in left ventricular ejection fraction (LVEF) recovery. Case Description: A 49-year-old female with past medical history of asthma initially presented to an outside hospital for palpitations, chest pain, and hypertension. Transthoracic echo (TTE) showed preserved left ventricle ejection fraction (LVEF) while cardiac MRI showed a LVEF of 43% with dilated left ventricle and diffuse global hypokinesis consistent with a dilated cardiomyopathy. She underwent a coronary angiogram demonstrating nonobstructive CAD. She was then discharged with readmission a month later at our hospital for chest tightness, palpitations, vomiting, weakness, and dizziness. Repeat TTE showed a drop in LVEF to 10-15%. She progressed to cardiogenic shock requiring BiPAP and inotrope initiation, with progressive shock and hypotension ultimately requiring Impella 5.5 and venoartrial ECMO. Abdominal imaging was notable for 4.7 x 4.2 cm right adrenal nodule and further workup with serum and urine metanephrines confirmed pheochromocytoma. While supported, the patient underwent right adrenalectomy with subsequent wean of mechanical circulatory support and biventricular recovery on TTE. Discussion: Pheochromocytoma-induced heart failure is a rare but potentially life-threatening complication from excess catecholamine effects on the myocardium. Pheochromocytomas should be considered in the evaluation of idiopathic heart failure even in the absence of symptoms related to catecholamine excess. Early detection, pharmacological management, and surgical resection may prevent progression of myocardial remodeling. Mechanical circulatory support can be a valuable adjunct in managing refractory heart failure in these patients by providing temporary hemodynamic stabilization while awaiting definitive tumor resection.

Abstract 4141445: Long-Term Predictive Value of 4D Flow MRI in Bicuspid Aortic Valve Patients: A 10-Year Assessment for Aortic Surgery Risk

Introduction: Bicuspid aortic valve (BAV) is associated with progressive ascending aorta (AAo) dilation, often leading to aneurysms, dissections, and ruptures. Thus, current guidelines recommend preventive surgery for AAo dilation. Recent 4D flow MRI studies show that BAV morphology causes abnormal transvalvular flow patterns, increasing wall shear stress (WSS), a trigger of aortic growth. Further studies have delineated areas of abnormally high WSS by comparing to estimates of matched controls, and show promise in detecting risk for aortic growth. However, since the long-term prognostic significance of this marker is unclear, we aimed to quantify WSS in BAV patients to assess its value in predicting the need for aortic surgery up to 10 years post-4D flow MRI acquisition. Methods: BAV patients without prior surgical intervention scanned before April 1, 2014 were identified. Using medical records, patients were categorized as ‘operated’ if they underwent aortic surgery post-scan and ‘non-operated’ if they were surgery-free for at least 10 years post-scan. 4D flow MRIs were processed with an AI pipeline, including 3D segmentation of the aorta, followed by peak velocity (PV) and WSS quantification in the AAo (Fig. 1A-C). Patient-specific WSS heatmaps were computed relative to a map based on the WSS of 10 or more sex and age-matched controls. Relative areas of elevated WSS in the AAo were then calculated (Fig. 1D-F). Results: 115 patients were included, with 73 non-operated (age: 42.5±11.5y, 49M) and 42 operated patients (age: 53.5±12.1y, 34M). The mean baseline mid-AAo diameters for non-operated and operated patients were 3.8±0.6 cm and 4.1±0.5 cm, respectively. Among operated patients, the mean scan to surgery time was 5.7±3.3y. All three 4D flow metrics were significantly higher in operated compared to non-operated patients: PV: 2.6±0.6 vs. 1.7±0.4 m/s (p<0.01); WSS: 2.2±0.5 vs. 1.6±0.4 Pa (p<0.01); relative area of high WSS on heatmaps: 31±12 vs. 15±13% (p<0.01). Conclusions: 4D flow MRI parameters provide long-term predictive value in BAV patients, as elevated peak velocity, wall shear stress, and relative area of high wall shear stress on heatmaps are associated with subsequent aortic surgery within 10 years post-scan.

Unusual Foreign Body in the Middle Ear: Surgical Removal of a Live Ant Entering the Tympanic Cavity Through an Ear Drum Perforation

This case report details the unusual occurrence of a live ant invading the middle ear cavity through a pre-existing perforation in the tympanic membrane of a 42-year-old female patient. She presented to an outpatient clinic with symptoms of sudden-onset tinnitus (“ringing”) and a foreign body sensation in her left ear. Otomicroscopy revealed an oval-shaped perforation in the posterior part of the left tympanic membrane, through which a dark, moving foreign object was observed in the middle ear. The object was identified as a live ant. Initial attempts to remove the insect under local anesthesia were unsuccessful, necessitating the patient’s admission for surgery. Under general anesthesia, an endoscopic tympanotomy was performed, and the ant was successfully removed without complications. The patient recovered and was discharged the following day. At her follow-up appointment, she remained symptom-free. This case highlights the rare yet possible occurrence of live foreign bodies entering the middle ear through tympanic perforations and the need for timely surgical intervention to prevent complications.

Accuracy of adult height predictions in patients with axial leg deviations using the Modified and the Abbreviated Modified Fels Knee System

Background The accurate estimation of residual growth is crucial for the appropriate timing of growth-guiding surgery in patients with axial leg deviations. Skeletal age methods such as the Modified and the Abbreviated Modified Fels Knee System were developed on historical patient cohorts and the applicability to the modern pediatric population with axial leg deviation has not yet been evaluated. Questions/purposes Are both final adult height prediction methods (the Modified Fels Knee System (FKS) and the Abbreviated Modified Fels Knee System (aFKS)) accurate to determine SA and the final adult height on long leg radiographs in patients with axial leg deviations? Which multiplier table shows highest association between predicted and true final adult body height? Do FKS- and aFKS- skeletal age determination methods improve final adult body height prediction accuracy compared to the simple use of chronological age? Methods A single center, retrospective study of 31 patients who underwent temporary hemiepiphysiodesis due to axial leg deviations in the frontal plane between 2018 and 2020 was conducted. Skeletal age at the time of surgery was determined on an anterior-posterior long leg X-ray using FKS and aFKS. Adult height predictions were calculated using three different multiplier tables (Paley et al., Sanders-Greulich and Pyle (SGP), Sanders-Peak Height Velocity (PHV)). The accuracy of adult height prediction was determined by comparing the mean differences and mean absolute differences between predicted and true adult height. Results All adult height predictions overestimated the true adult height. The final height prediction using aFKS and the SGP multiplier showed the lowest overestimation (mean 3.2 cm, SD 5.5 cm). The PHV multiplier table showed the highest correlation between predicted and true adult height (FHPRE_FKS_PHV: r = 0.913, p < 0.001 and FHPRE_aFKS_PHV: r = 0.862, p < 0.001). The simple use of chronological age at the time of surgical intervention (CASI) with the Paley multiplier table showed the highest median delta absolute values and lowest correlations with true adult height (median 7.4 cm, 25%-75% percentile: 3.5–10.0 cm, r = 0.838, p < 0.001). Nevertheless, no significant differences in delta absolute values between various adult height predictions methods could be shown. Conclusions Overall, the results of the present retrospective cohort study show that there was no significant improvement in final height prediction accuracy when using the FKS or the aFKS method compared to the simple use of chronological age. One reason could be that patients with varus/valgus malalignment have specific growth characteristics that are not accounted for in multiplier tables or the FKS and aFKS method. Since there is no significant difference in prediction accuracy between the methods, the choice of method may depend on other factors, such as clinical preference or availability of resources. However, due to the small sample size, the study cannot definitively rule out potential differences between the prediction methods, and larger studies are required to validate these findings.

Abstract 4143267: Bicaudal-C Homolog 1 Plays a Significant Role in Cardiac Development and Congenital Heart Defects

Background: Congenital heart defects (CHDs) are the most common birth defects globally and often require palliative surgical interventions with limited long-term effectiveness. Prenatal detection of CHDs is challenging due to the absence of heart failure signs in most fetuses. Thus, early detection methods and therapeutic drugs to correct abnormal heart development are crucial. We have discovered that the RNA-binding protein Bicaudal-C homolog 1 (Bicc1) influences normal and abnormal heart development. Bicc1 is involved in post-transcriptional regulation and interacts with RNA interference (RNAi) components. While its role in left-right patterning, kidney development, and the interaction with PKD genes ( Pkd1 and Pkd2 ) is documented, the role of Bicc1 and its expression in heart development and whether it relies on interaction with Pkd1/Pkd2 are not understood. Methods and Results: To start addressing these knowledge gaps, we used a transgenic mouse line with an in-frame fusion of Bicc1 and the LacZ reporter gene to perform β-galactosidase staining, RNAscope and immunostaining to identify the cardiac cell types expressing Bicc1 . High Bicc1 expression was observed in embryonic and neonatal hearts, particularly in the ventricles, atria, and endothelial cells of blood vessels. Expression decreased in adulthood but persisted at basal levels. We observed that Bicc1 knockout (KO) developed heterotaxy of the heart and enlarged atria. Next, to elucidate the gene and miRNA regulatory networks involved in cardiac development disrupted by the absence of Bicc1, we carried out RNA- and miRNA-seq on hearts from wild-type and Bicc1 KO embryonic hearts at different developmental stages. Several genes and miRNAs associated with ciliopathy and heterotaxy, including miR-196 , Hand1 , and Lefy2, were significantly altered in Bicc1 KO mice. Moreover, as reported for the kidney, Pkd2 mRNA expression was altered in Bicc1 KO mice, while Pkd1 expression remained unchanged. Finally, we detected changes linked to lipid metabolism and related pathways, such as members of aldehyde dehydrogenase ( Adlh1a ) and cytochrome P450 family ( Cyp5a1 ), that were altered in the absence of Bicc1 . Conclusions: Our study reveals additional role(s) for Bicc1 in heart development suggesting its involvement in regulating heart metabolism in fetuses. These findings provide a conceptual basis for future investigations into the function of Bicc1 in heart development and how its disruption contributes to CHDs.

Abstract 4138310: Successful Endovascular Closure of Ascending Aortic Pseudoaneurysm Using Atrial Septal Defect Occluder

Introduction: Ascending aortic pseudoaneurysms are mostly related to either surgery or non-surgical trauma. Any pseudoaneurysm arising from graft anastomoses, regardless of size or location, must be repaired due to the potential for catastrophic rupture. Traditional surgical intervention has a high mortality rate, but percutaneous treatment has emerged as an alternative. We present such a case of pseudoaneurysm treated by percutaneous intervention using a 6-mm Amplatzer device. Case: A 77-year-old female with a history of type A aortic dissection s/p emergent repair with a 32 mm tube graft one year ago presented with chest pain radiating to her back. Initial vital signs showed a BP of 185/105, SaO2 98% on RA, 98.3 F, HR 98 bpm, and RR 24/min. A chest CT scan suggested a pseudoaneurysm at the proximal anastomotic site of the aortic graft (Figs. 1A and B). Serial troponin and EKGs were unremarkable for acute ischemia. Multiple quaternary centers declined intervention due to the high risk of redo sternotomy for open repair and patient frailty. After multidisciplinary discussions, it was felt that percutaneous closure with an Amplatzer device was possible without coronary obstruction. In the catheterization lab, a TEE probe was placed to visualize the pseudoaneurysm of the ascending aorta (Fig. 1C). Angiography showed the aneurysm coming off the posterior aorta just above the noncoronary cusp, with the neck measuring ~6 mm (Fig. 1D). The aneurysm was successfully engaged using an 8-French sheath and an 8-French AL1. Based on measurements from the TEE and the angiogram, a 6 mm ASO device was used. After device deployment and release, aortograms showed that the pseudoaneurysm was excluded (Fig. 1H). Assessment with TEE and CTA showed no residual flow in the pseudoaneurysm (Fig. 1 E–G). Conclusion: Using an atrial septal occluder, endovascular intervention may be a safe and effective alternative to surgery for treating the ascending aortic pseudoaneurysm, especially in patients with a high prohibitive surgical risk. Longitudinal follow-ups are needed to comment on long-term mortality benefits for these individuals.

Abstract 4148074: Radial Artery Pseudoaneurysm Following Transradial Cardiac Catheterization: A Systematic Review and Case Report

Introduction/Background: Transradial cardiac catheterization (TRC) is recommended for patients with acute coronary syndrome over femoral artery catheterization. Randomized controlled trials show TRC has significantly lower rates of bleeding, vascular complications, and mortality in high-risk acute coronary syndrome patients. However, vascular complications like radial artery spasm, occlusion, arteriovenous fistula, perforation, and pseudoaneurysm (PSA) can still occur. Despite TRC's widespread adoption, recent data summarizing radial artery pseudoaneurysm post-TRC is lacking. Research Question/Hypothesis This review aims to identify at-risk patients, present a case of catheterization-related radial artery pseudoaneurysm, and provide diagnostic and management insights. We hypothesize that older patients with hypertension are at higher risk and that early detection and management are associated with low complication rates. Methods/Approach: Systematic searches were conducted in PubMed, Web of Science, EMBASE, and CINAHL databases. Two researchers independently selected articles, extracted data, and evaluated study quality on RA PSA post-TRC (2003–2023). A third reviewer resolved conflicts. The Joanna Briggs Institute (JBI) tool was used to evaluate bias risk. Additionally, a case report is presented. Results: From 3,262 records, 43 studies were selected, involving 67 patients (58.8% female, median age 73.5 years). Hypertension (39.5%) and atrial fibrillation (27.9%) were the most common comorbidities. Percutaneous interventions like stenting and angioplasty caused 58.1% of cases; diagnostic catheterizations accounted for 37.2%. Ultrasonography diagnosed 83.7% of cases. Symptoms appeared a few hours to four months post-TRC, with pulsatile mass (21.4%) and swelling (14.3%) being the most common, and pain and ecchymosis at 2.4% each. More than half of the patients (51.2%) required surgical intervention, but 66.7% recovered without deficits. Severe complications were rare, affecting fewer than 5%. Conclusions: A literature review of 43 articles with 67 patients suggests older female patients with hypertension may be more prone to radial artery pseudoaneurysm post-TRC. It typically presents as a pulsatile, painful swelling detectable by ultrasound. This complication precludes the use of the radial artery as a conduit for coronary artery bypass grafting. The review highlights the importance of vigilant post-catheterization monitoring to enable early detection and treatment.

An ayurvedic approach to the management of Fissure-in-ano: A case Study

Background: In today's sedentary lifestyle, coupled with unhealthy dietary habits and stress, digestive disorders such as Fissure-in-ano have become prevalent. Fissure-in-ano is a longitudinal tear in the anal canal, most commonly occurring in the posterior midline, characterized by severe pain, burning sensation, and occasional bleeding. In Ayurveda, this condition aligns with Parikartika, often caused by improper administration of therapies like Basti (enema) or Virechana (purgative). Case Study: It explores the efficacy of per rectal Administration of Kaseesadi Taila for the management of Parikartika in a 35-year-old female patient presenting with anal pain, burning, and rectal bleeding post-defecation. Materials & Methods: It involved daily rectal Administration of Kaseesadi Taila (10ml) for 7 days. Results: It showed significant improvement by day 3, with complete relief of symptoms and healing of the fissure by day 7. The therapeutic benefits of Kaseesadi Taila are attributed to its Lekhana (scraping), Shodhana (cleansing), and Ropana (healing) properties, which promote wound healing, reduce inflammation, and facilitate easier bowel movements. Conclusion: Kaseesadi Taila is an effective, cost-efficient treatment for fissure-in-ano, providing significant symptom relief without the drawbacks of conventional surgical interventions.

Isolated hydatid cyst in the medial rectus muscle: unveiling a rare orbital occurrence

Abstract Background Orbital hydatid disease, while rare, should be included in the differential diagnosis of unilateral proptosis, particularly in endemic areas. Accurate diagnosis and comprehensive management are essential for effective treatment and favorable long-term outcomes. Case Presentation A 12-year-old boy presented with a one-month history of diplopia and left-sided proptosis. A CT scan revealed a cystic mass within the left medial rectus muscle. Surgical intervention confirmed the presence of a hydatid cyst following cyst rupture and irrigation with hypertonic saline. The patient underwent a two-month course of albendazole therapy. Initially, the patient experienced persistent exotropia and diplopia, but at the three-year follow-up, he exhibited no diplopia or proptosis and only mild residual exotropia. Conclusion This case underscores the importance of considering orbital hydatid cysts in the differential diagnosis of unilateral proptosis in endemic regions. Heightened awareness, accurate diagnosis, and a tailored therapeutic approach, including surgical removal and antiparasitic treatment, are crucial for successful management and improved long-term outcomes.

Clinical Management of Uterine Prolapse in a Multiparous Persian Cat: A Case Report

This case report deals with the clinical management of uterine prolapse in a 3.5 years old Persian cat with the history of prior parturition. The prolapsed mass was displaying congestion, enlargement, edema and mild straining with no lacerations or injuries. After thorough cleaning, reduction of edema and antiseptic dressing, the prolapsed uterus was repositioned properly. Purse string suture was applied to prevent reoccurrence. The queen showed good response to the manual correction, with no complications. This report demonstrates effective clinical management of postpartum uterine prolapse by manual repositioning in a queen cat avoiding surgical intervention.

Novel Algorithm for Surgical Management of Cervical Ossification of Posterior Longitudinal Ligament: A Retrospective Cohort Study With 2‐Year Follow‐Up

ABSTRACTObjectWith the development of new technologies, the surgical algorithm for ossification of posterior longitudinal ligament (OPLL) in the cervical spine also needs to be updated. The aim of this study is to elucidate a new surgical classification algorithm to guide the choice of surgical approaches for cervical OPLL based on its location and extent. In this algorithm, anterior controllable antedisplacement and fusion (ACAF) will be used as a new surgical option.MethodsThis is a single‐centered, retrospective, cohort study utilizing a novel algorithm based on the following three criteria: (1) the positional relationship between ossification and uncinate process (UP), (2) the K‐line, and (3) the ossification segment for surgical decision‐making. Patients diagnosed with cervical OPLL who received surgical intervention guided by the algorithm were included. Patient demographics, Japanese Orthopedic Association (JOA) scores, surgical time, imaging data before and 2 years after surgery, and the occurrence of complications were extracted from the database. Paired t‐test was used for intragroup comparison, and one‐way ANOVA test was used for the intergroup analyses.ResultsBased on this novel algorithm, 15 patients with Type I, 8 patients with Type II a, 2 patients with Type II b1, 5 patients with Type II b2 were included. The decision‐making for the surgical techniques used in each patient followed the recommendation of the novel algorithm. The postoperative JOA scores of all types of patients improved significantly (p < 0.05), and the invasion rates of vertebral canal had also been significantly reduced (p < 0.05). In terms of restoring cervical curvature, patients with Type I (receiving ACAF) and Type II b2 (receiving laminectomy with instrumented fusion) benefited more from surgery (p < 0.05).ConclusionA new algorithm guiding the choice of surgical approach for cervical OPLL was validated in a series of 30 patients. Through this analysis, we obtained on their clinical outcomes and complications. ACAF surgery is an ideal choice for Type I patients, with ossification located between UPs, while for patients with ossification exceeding UPs, it is better to perform anterior cervical corpectomy and fusion or posterior surgery.

Prognostic value of surgical treatment in elderly patients with ulcerative colitis‐associated colorectal cancer: A subanalysis of a nationwide Japanese multicenter study

AbstractAimOur study aimed to examine the characteristics of elderly patients diagnosed with ulcerative colitis‐associated colorectal cancer (UAC) and evaluate the impact of surgical intervention on prognosis.MethodsA total of 1086 patients diagnosed with UAC between 1980 and 2020 were retrospectively enrolled. Data were collected through the Japanese Society for Cancer of the Colon and Rectum project. The patients were divided into two groups: 248 elderly patients in the E‐UAC group and 838 nonelderly patients in the NE‐UAC group. Patients aged >65 y at cancer diagnosis were considered elderly.ResultsThe recurrence rate did not differ between the two groups. Segmental resection was the only common independent risk factor for recurrence in both the E‐UAC and the NE‐UAC groups. The E‐UAC patients had significantly better 5‐y disease‐specific survival (DSS) than the NE‐UAC patients (94.7% vs 91.0%, p = 0.04). There were no differences in 5‐y recurrence‐free survival (RFS; 89.3% vs 86.6%, respectively, p = 0.24) or overall survival (OS; 88.8% vs 89.6%, p = 0.50). The E‐UAC patients who underwent segmental resection had poorer RFS than those who underwent total proctocolectomy, but there were no significant differences in DSS or OS.ConclusionDespite the elevated risk of cancer recurrence observed in the UAC patients who underwent segmental resection in both the E‐UAC the NE‐UAC groups, our findings suggested that segmental resection may be a viable alternative to total proctocolectomy in terms of survival rate for the E‐UAC patients.

Enhancing Outcomes and Efficiency in Large Epidermal Cyst Management: Quality Improvement Approach in Primary Care

Background: Epidermal cysts are common benign lesions encountered in primary care, especially in minor surgery clinics. The management of large epidermal cysts (>5 cm in diameter) poses significant challenges, including surgical intervention requirements, potential for complications, and impacts on patient care and clinic workflow. The prevalence of these cysts underlines the need for optimised management strategies that are essential for enhancing patient outcomes and clinic efficiency. This quality improvement initiative sought to better manage large epidermal cysts in primary care settings. Patients and methods: The initiative utilised the Plan-Do-Study-Act (PDSA) cycle over three distinct phases, with an emphasis on improving surgical techniques and postoperative care, optimising clinic workflow, and enhancing patient education and involvement. Over the course of this eighteen-month study, 100 patients who required surgical excision of large epidermal cysts were included. The interventions focused on standardising surgical protocols, implementing a new scheduling system, and developing comprehensive educational materials for patients. Results: The programme contributed to major efficiency gains for surgeries: the average operative time was reduced from 45 min to 30. The postoperative complication rate decreased dramatically while patient and clinician satisfaction went up, as did clinic throughput. With patient education enhancements, follow-up adherence rose to 92% while the postoperative complication rate declined from 18% to 9% with the overall approach to patient engagement. Conclusions: The successful application of the PDSA cycles in this work demonstrates that quality improvement methodologies have a potential role in optimising management for large epidermal cysts in primary care settings. Developed interventions can therefore be put into routine care that will indeed improve patient outcome, clinician experience, and operational efficiency in minor surgery clinics.

Leiomyosarcoma of the inferior vena cava: case report

Introduction and Importance: Leiomyosarcomas of the inferior vena cava are exceedingly rare tumors, presenting diagnostic dilemmas due to their nonspecific clinical features. This case report aims to shed light on the challenges associated with diagnosing and managing such tumors, emphasizing the importance of a multidisciplinary approach. This article uses SCARE2023 criteria as a framework to sort out a case report in order[1]. Case Presentation: We present a case of leiomyosarcoma of the inferior vena cava in a patient presenting with abdominal pain. Initial clinical signs, supported by computed tomography (CT) and magnetic resonance imaging (MRI), led to the suspicion of the tumor. Histological analysis confirmed the diagnosis, prompting surgical intervention. Clinical Discussion: The diagnosis of tumors within the inferior vena cava is often challenging due to their nonspecific presentation. Imaging modalities such as CT and MRI play an important role in describing the extent of the tumor and guiding surgical planning. Histological analysis remains supreme for definitive diagnosis. Surgical resection, aimed at complete excision, is the keystone of treatment to minimize the risk of recurrence. Conclusion: Leiomyosarcomas of the inferior vena cava pose diagnostic and therapeutic challenges due to their rarity and nonspecific clinical presentation. A comprehensive approach integrating clinical assessment, imaging, and histological analysis is essential for accurate diagnosis and optimal management. Multidisciplinary collaboration is key for navigating the complexities associated with these rare vascular neoplasms, ensuring positive patient outcomes.

Clinical case of malignant paraganglioma treatment involving carotid artery replacement with a prosthesis

One of the rare neuroendocrine vascular neoplasms is paraganglioma. This tumor is diagnosed in 0.5 % of all cases of head and neck tumors. The treatment of choice for paraganglioma is open surgical intervention. The number of complications after this surgery remains high. The rarity of paraganglioma dictates the necessity of personalized approach to each patient with this pathology.The article presents a clinical case of successful treatment of malignant paraganglioma. After open surgical intervention, control of the long-term results is necessary to prevent development of malignant process and disease recurrence.

Integrated surgical intervention for intradural extramedullary hemangioblastoma of the cervical spine: a case report and literature review

IntroductionThe incidence of hemangioblastoma is low, constituting only 1-5% of all spinal cord tumors. Specifically, intradural extramedullary hemangioblastoma without Von Hippel-Lindau syndrome represents an exceedingly rare condition.MethodsWe report the first documented case of cervical intradural extramedullary hemangioblastoma in China. A 53-year-old male patient presented with a 3-year history of mild right hemiplegia, segmental muscle strength and sensation impairment, and a positive pyramidal tract sign. MRI showed an abnormal oval signal focus in the intradural and extramedullary region at the C6-C7 vertebral level. Before surgery, angiography was performed to identify the supplying arteries and draining veins. Subsequent interventional therapy achieved over 90% occlusion of blood vessels, creating optimal conditions for complete resection of the spinal tumor.ResultsThe patient demonstrated satisfactory postoperative recovery with significant restoration of sensory and motor functions. Pathological examination showed a significant upregulation of CD31 in tumor cells and a substantial presence of the neuro-specific marker S100 in the tumor stroma, consistent with the diagnostic criteria for spinal hemangioblastoma.ConclusionThe rarity of cervical intradural extramedullary hemangioblastoma without Von Hippel-Lindau syndrome was reaffirmed by a comprehensive review of the existing literature. Complete tumor resection remains the optimal approach for managing this uncommon condition, generally resulting in a favorable prognosis. Traditional open fenestration surgery is linked to elevated risks of bleeding and trauma. Meanwhile, endovascular injection of embolic agents may lead to residual lesions and an increased risk of recurrence. Therefore, we recommend a one-time combined treatment conducted in a hybrid operating room to achieve complete resection and effectively reduce intraoperative bleeding risk. Despite presenting challenges and requiring high proficiency, we still recommend this type of combined surgery as a suitable therapeutic option for such diseases.
