RESUMO

BACKGROUND: Temporary abdominal closure (TAC) techniques are essential in managing open abdomen cases, particularly in damage control surgery. Skin-only closure (SC) and Bogota bag closure (BBC) are commonly used methods for TAC, but their comparative effectiveness in achieving primary fascial closure (PFC) remains unclear. The objective of this study was to evaluate the rates of PFC between patients undergoing SC and BBC techniques for TAC in peritonitis or abdominal trauma cases at a tertiary care hospital. METHODS: A retrospective cross-sectional study was conducted at the Surgical A Unit of Hayatabad Medical Complex, Peshawar, from January 2022 to July 2023. Approval was obtained from the institutional review board, and patient consent was secured for data use. Patients undergoing temporary abdominal closure using either skin-only or Bogota bag techniques were included. Exclusions comprised patients younger than 15 or older than 75 years, those with multiple abdominal wall incisions, and those with prior abdominal surgeries. Data analysis utilized SPSS version 25. The study aimed to assess outcomes following damage control surgery, focusing on primary fascial closure rates and associated factors. Closure techniques (skin-only and Bogota bag) were chosen based on institutional protocols and clinical context. Indications for damage control surgery (DCS) included traumatic and non-traumatic emergencies. Intra-abdominal pressure (IAP) was measured using standardized methods. Patients were divided into SC and BBC groups for comparison. Criteria for reoperation and primary fascial closure were established, with timing and technique determined based on clinical assessment and multidisciplinary team collaboration. The decision to leave patients open during the index operation followed damage control surgery principles. RESULTS: A total of 193 patients were included in this study, with 59.0% undergoing skin-only closure (SC) and 41.0% receiving Bogota bag closure (BBC). Patients exhibited similar demographic characteristics across cohorts, with a majority being male (73.1%) and experiencing acute abdomen of non-traumatic origin (58.0%). Among the reasons for leaving the abdomen open, severe intra-abdominal sepsis affected 51.3% of patients, while 42.0% experienced hemodynamic instability. Patients who received SC had significantly higher rates of primary fascial closure (PFC) compared to BBC (85.1% vs. 65.8%, p = 0.04), with lower rates of fascial dehiscence (1.7% vs. 7.6%, p = 0.052) and wound infections (p = 0.010). Multivariate regression analysis showed SC was associated with a higher likelihood of achieving PFC compared to BBC (adjusted OR = 1.7, 95% CI: 1.3-3.8, p < 0.05). CONCLUSION: In patients with peritonitis or abdominal trauma, SC demonstrated higher rates of PFC compared to BBC for TAC in our study population. However, further studies are warranted to validate these results and explore the long-term outcomes associated with different TAC techniques.

RESUMO

Sir William Macewen, a Scottish surgeon, made significant contributions to neurosurgery, beginning with his successful brain tumor resection in 1879. Born in 1848, Macewen's upbringing in a maritime family fostered a practical approach to learning. Macewen's pivotal brain tumor surgery demonstrated his adherence to antiseptic practices and precise localization techniques. Controversy arose regarding his precedence in neurosurgery, which he addressed through meticulous documentation and public presentations. His diagnostic prowess extended to cases of cerebral abscesses and intracranial conditions, relying on clinical observations rather than imaging technology. His 1893 monograph on brain infections remains influential in neurosurgery. Beyond neurosurgery, Macewen was innovative in asepsis, hernia repair, and bone surgery. His legacy as a clinical educator and advocate for surgical advancements earned him widespread recognition. This historical review aimed to explore and evaluate the published literature regarding Macewen's early brain tumor surgeries, seeking to establish his precedence over later surgeons including Godlee and Bennett.

RESUMO

BACKGROUND: Pineal apoplexy, alternatively referred to as pineal hemorrhage or pineal gland hemorrhagic stroke, is an infrequent pathologic condition characterized by bleeding within the pineal gland. In this review, we encompass the primary factors contributing to this uncommon ailment. METHODS: The retrieval of pertinent research, including patients with pineal apoplexy, was conducted through PubMed, Google Scholar, and Scopus databases. This study exclusively incorporated comprehensive articles written in the English language. The search encompassed the MeSH terms "pineal apoplexy" and "pineal hemorrhage." RESULTS: A total of 41 articles were identified, encompassing a collective sample size of 57 patients. The median age of the patients in the study was 30 years, with a range spanning from 1 to 73 years. There were 27 males, representing 47.4% of the participants. The study identified the most often reported symptoms as headache (49; 86%), nausea/vomiting (19; 33.3%), and Parinaud's syndrome (16; 28.1%). The treatment options encompass several approaches, including open resection, shunting, ventriculostomy, endoscopic aspiration, and conservative care. In the conducted study, a notable number of patients, amounting to 45 cases (78.9%), indicated an amelioration of their symptoms upon their discharge. CONCLUSION: Data from a cohort of 57 cases provide insights into symptoms, lesions, treatments, and outcomes. Management approaches range from conservative measures to surgical interventions, with prognosis hinged on timely intervention. This investigation serves as a valuable resource for clinicians and researchers, underscoring the need for early diagnosis before permanent neurologic dysfunction happens and tailored treatments for optimal outcomes in pineal apoplexy cases.

RESUMO

Gastric cancer (GC) represents a major global health burden and is responsible for a significant number of cancer-related fatalities. Its complex nature, characterized by heterogeneity and aggressive behaviour, poses considerable challenges for effective diagnosis and treatment. Single-cell RNA sequencing (scRNA-seq) has emerged as an important technique, offering unprecedented precision and depth in gene expression profiling at the cellular level. By facilitating the identification of distinct cell populations, rare cells and dynamic transcriptional changes within GC, scRNA-seq has yielded valuable insights into tumour progression and potential therapeutic targets. Moreover, this technology has significantly improved our comprehension of the tumour microenvironment (TME) and its intricate interplay with immune cells, thereby opening avenues for targeted therapeutic strategies. Nonetheless, certain obstacles, including tumour heterogeneity and technical limitations, persist in the field. Current endeavours are dedicated to refining protocols and computational tools to surmount these challenges. In this narrative review, we explore the significance of scRNA-seq in GC, emphasizing its advantages, challenges and potential applications in unravelling tumour heterogeneity and identifying promising therapeutic targets. Additionally, we discuss recent developments, ongoing efforts to overcome these challenges, and future prospects. Although further enhancements are required, scRNA-seq has already provided valuable insights into GC and holds promise for advancing biomedical research and clinical practice.

RESUMO

Spine surgery is continually evolving, with the application of new technologies often serving as a catalyst for improved clinical outcomes. Exoscope-assisted spinal surgery has recently emerged as a notable technological advancement offering a refined approach to visualisation, thereby potentially contributing to improved surgical precision, reduced complication rates, and optimised patient outcomes. The application of exoscopes have improved spine surgeries such as spinal fusion procedures, decompression surgeries, instrumentation surgeries, minimally invasive and complex surgeries. These improvements include enhanced visualisation, improved ergonomics, improved surgical precision, reduced operation times and postoperative infection rates. The integration of robotics in exoscope-assisted spine surgery enables autofocus function, ensuring the integrity of the sterile field, providing superior image quality, resolution, and three-dimensional perception. However, challenges such as decrease in depth perception and the lack of long-term follow-up data hinder its widespread adoption. Ethical considerations regarding patient safety, technology dependency, and health inequity add another dimension to these challenges. Despite these challenges, exoscope-assisted spine surgery holds significant potential for transforming clinical practice and improving patient outcomes. This review seeks to provide a concise overview of the benefits and limits of exoscope-assisted spine surgeries, while highlighting its challenges and ethical considerations. Addressing these limitations by conducting large-scale clinical trials and exploring the integration of artificial intelligence (AI) could assist in realising the potential of exoscopes in spine surgery."

RESUMO

Using the particular nature of melanoma mutanomes to develop medicines that activate the immune system against specific mutations is a game changer in immunotherapy individualisation. It offers a viable solution to the recent rise in resistance to accessible immunotherapy alternatives, with some patients demonstrating innate resistance to these drugs despite past sensitisation to these agents. However, various obstacles stand in the way of this method, most notably the practicality of sequencing each patient's mutanome, selecting immunotherapy targets, and manufacturing specific medications on a large scale. With the robustness and advancement in research techniques, artificial intelligence (AI) is a potential tool that can help refine the mutanome-based immunotherapy for melanoma. Mutanome-based techniques are being employed in the development of immune-stimulating vaccines, improving current options such as adoptive cell treatment, and simplifying immunotherapy responses. Although the use of AI in these approaches is limited by data paucity, cost implications, flaws in AI inference capabilities, and the incapacity of AI to apply data to a broad population, its potential for improving immunotherapy is limitless. Thus, in-depth research on how AI might help the individualisation of immunotherapy utilising knowledge of mutanomes is critical, and this should be at the forefront of melanoma management.

RESUMO

Background and Aims: Intracranial surgeries are pivotal in treating cerebral pathologies, particularly in resource-limited contexts, utilizing techniques such as craniotomy, transsphenoidal approaches, and endoscopy. However, challenges in low and middle income countries (LMICs), including resource scarcity, diagnostic delays, and a lack of skilled neurosurgeons, lead to elevated perioperative mortality (POM). This review seeks to identify major contributors to these challenges and recommend solutions for improved patient outcomes in neurosurgical care within LMICs. Methods: This review examines POM in LMICs using a detailed literature search, focusing on studies from these regions. Databases like PubMed, EMBASE, and Google Scholar were utilized using specific terms related to "intracranial surgery," "perioperative mortality," "traumatic brain injuries," and "LMICs." Inclusion criteria covered various study designs and both pediatric and adult populations while excluding stand-alone abstracts and case reports. Results: POM rates for intracranial surgeries differ widely across many low and middle-income regions: Africa sees rates from 2.5% to 39.1%, Asia between 3.6% and 34.8%, and Latin America and the Caribbean have figures ranging from 1.3% to 12%. The POM rates in LMICs were relatively higher compared to most first-world countries. The high POM rates in LMICs can be attributed to considerable delays and compromises in neurosurgical care delivery, exacerbated by late diagnoses and presentations of neurosurgical pathologies. This, coupled with limited resources, underdeveloped infrastructure, and training gaps, complicates intracranial disease management, leading to elevated POM. Conclusion: Intracranial POM is a pronounced disparity within the neurosurgical field in LMICs. To mitigate intracranial POM, it is imperative to bolster healthcare infrastructure, amplify personnel training, foster global partnerships, and harness technologies like telemedicine. Tackling socioeconomic obstacles and prioritizing early detection through sustained funding and policy shifts can substantially enhance patient outcomes.

RESUMO

Cardiovascular disease (CVD) and cancer are leading causes of mortality worldwide, traditionally linked through adverse effects of cancer therapies on cardiovascular health. However, reverse cardio-oncology, a burgeoning field, shifts this perspective to examine how cardiovascular diseases influence the onset and progression of cancer. This novel approach has revealed a higher likelihood of cancer development in patients with pre-existing cardiovascular conditions, attributed to shared risk factors such as obesity, a sedentary lifestyle, and smoking. Underlying mechanisms like chronic inflammation and clonal hematopoiesis further illuminate the connections between cardiovascular ailments and cancer. This comprehensive narrative review, spanning a broad spectrum of studies, outlines the syndromic classification of cardio-oncology, the intersection of cardiovascular risk factors and oncogenesis, and the bidirectional dynamics between CVD and cancer. Additionally, the review also discusses the pathophysiological mechanisms underpinning this interconnection, examining the roles of cardiokines, genetic factors, and the effects of cardiovascular therapies and biomarkers in cancer diagnostics. Lastly, it aims to underline future directives, emphasising the need for integrated healthcare strategies, interdisciplinary research, and comprehensive treatment protocols.

RESUMO

BACKGROUND: It is extremely unusual for multiple tumors to arise from different cell types and occur at the same time inside the brain. It is still unknown whether or not the coexistence of meningioma and glioblastoma is connected in any way or if their simultaneous appearance is merely a coincidence. OBJECTIVE: We conduct a comprehensive literature review on cases of concurrent meningioma and glioblastoma occurrence to elucidate the underlying concepts that may constitute this coexistence. METHODS: We searched for articles on the topic of glioblastoma coexisting with meningioma in Google Scholar, PubMed, and Scopus. First, the initial literature searches were conducted for study selection and the data collection processes. After evaluating the title and abstract, the papers were selected. RESULTS: We analyzed 21 studies describing 23 patients who had both glioblastoma and meningioma. There were ten male patients (47.6 %) and thirteen female patients (61.9 %). The mean age of patients at diagnosis was 61 years old (the range 30 to 86). In 17 cases, both tumors were in the same hemisphere (80.9 %). In 5 cases, they were in the other hemisphere (23.8 %), and in one case, the glioblastoma was in the left hemisphere and the olfactory meningioma was In 5 cases, they were in the other hemisphere (23.8 %), and in one case, the glioblastoma was in the left hemisphere and the olfactory meningioma was in the anterior cranial fossa. In 61.9 % of cases, headache was the predominant symptom. CONCLUSION: Understanding the unique challenges posed by the coexistence of glioblastoma and meningioma is crucial for developing effective treatment strategies. Further investigation into the underlying molecular mechanisms and genetic factors involved in this rare occurrence could pave the way for personalized therapies tailored to each patient's specific needs.

RESUMO

Thyroid cancer, a prevalent form of endocrine malignancy, has witnessed a substantial increase in occurrence in recent decades. To gain a comprehensive understanding of thyroid cancer at the single-cell level, this narrative review evaluates the applications of single-cell RNA sequencing (scRNA-seq) in thyroid cancer research. ScRNA-seq has revolutionised the identification and characterisation of distinct cell subpopulations, cell-to-cell communications, and receptor interactions, revealing unprecedented heterogeneity and shedding light on novel biomarkers for therapeutic discovery. These findings aid in the construction of predictive models on disease prognosis and therapeutic efficacy. Altogether, scRNA-seq has deepened our understanding of the tumour microenvironment immunologic insights, informing future studies in the development of effective personalised treatment for patients. Challenges and limitations of scRNA-seq, such as technical biases, financial barriers, and ethical concerns, are discussed. Advancements in computational methods, the advent of artificial intelligence (AI), machine learning (ML), and deep learning (DL), and the importance of single-cell data sharing and collaborative efforts are highlighted. Future directions of scRNA-seq in thyroid cancer research include investigating intra-tumoral heterogeneity, integrating with other omics technologies, exploring the non-coding RNA landscape, and studying rare subtypes. Overall, scRNA-seq has transformed thyroid cancer research and holds immense potential for advancing personalised therapies and improving patient outcomes. Efforts to make this technology more accessible and cost-effective will be crucial to ensuring its widespread utilisation in healthcare.

RESUMO

Single-cell ribonucleic acid sequencing (scRNA-seq) has emerged as a transformative technology in neurological and neurosurgical research, revolutionising our comprehension of complex neurological disorders. In brain tumours, scRNA-seq has provided valuable insights into cancer heterogeneity, the tumour microenvironment, treatment resistance, and invasion patterns. It has also elucidated the brain tri-lineage cancer hierarchy and addressed limitations of current models. Neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis have been molecularly subtyped, dysregulated pathways have been identified, and potential therapeutic targets have been revealed using scRNA-seq. In epilepsy, scRNA-seq has explored the cellular and molecular heterogeneity underlying the condition, uncovering unique glial subpopulations and dysregulation of the immune system. ScRNA-seq has characterised distinct cellular constituents and responses to spinal cord injury in spinal cord diseases, as well as provided molecular signatures of various cell types and identified interactions involved in vascular remodelling. Furthermore, scRNA-seq has shed light on the molecular complexities of cerebrovascular diseases, such as stroke, providing insights into specific genes, cell-specific expression patterns, and potential therapeutic interventions. This review highlights the potential of scRNA-seq in guiding precision medicine approaches, identifying clinical biomarkers, and facilitating therapeutic discovery. However, challenges related to data analysis, standardisation, sample acquisition, scalability, and cost-effectiveness need to be addressed. Despite these challenges, scRNA-seq has the potential to transform clinical practice in neurological and neurosurgical research by providing personalised insights and improving patient outcomes.

RESUMO

Intracranial aneurysms, affecting 2%-5% of the population, pose a significant challenge to neurosurgeons due to their potential to cause subarachnoid haemorrhage and high mortality rates. Intraoperative angiography is necessary for effective surgical planning and indocyanine green video angiography (ICG-VA) has emerged as a useful tool for real-time visualization of aneurysmal blood flow, aiding in better planning for potential blood flow and detection of aneurysm remnants. This mini narrative review explores the application of ICG-VA in intracranial aneurysm surgery. Compared with conventional dye-based angiography, ICG-VA is safer, more effective and more cost-effective. It can assess haemodynamic parameters, cerebral flow during temporary artery occlusion, completeness of clipping and patency of branch vessels. However, implementing ICG-VA in low- and middle-income countries presents challenges such as financial constraints, limited access to training and expertise, patient selection and consent issues. Addressing these obstacles requires capacity-building, training programmes for neurosurgeons and multidisciplinary teams, technology transfer, equipment donations, public-private partnerships, continued research and development, reducing conventional dye usage, reducing ICG wastage, exploring mechanisms to reuse ICG dyes and advocating for increased government funding and healthcare budgets.

RESUMO

The global refugee community, including those forced to flee due to persecution, conflict, or violence, faces significant challenges in accessing healthcare, resulting in a higher prevalence of surgical disease. These challenges have a profound impact on morbidity and mortality rates, particularly in low- and middle-income countries where many immigrants seek refuge. Limited availability of medical facilities, an inadequate surgical workforce, financial constraints and linguistic and cultural barriers all contribute to reduced access to healthcare. Limited access to competent healthcare leads to poor health outcomes, increased morbidity and mortality rates and suboptimal surgical results for refugees. To address these challenges, a multifaceted approach is necessary. This includes increased funding for healthcare initiatives, workforce recruitment and training and improved coordination between aid organisations and local healthcare systems. Strategies for managing surgical conditions in the global refugee community encompass the development of targeted public health programmes, removing legal barriers, establishing healthcare facilities to enhance surgical access and prioritising disease prevention among refugees.

RESUMO

Craniomaxillofacial trauma (CMFT) is a type of injury that affects the face, neck, and scalp, and includes facial bone fractures, dentoalveolar trauma, and soft tissue injuries. Work, traffic accidents, sports, and daily activities commonly cause these injuries. However, they are widespread in war-torn countries where armed conflict leads to a high incidence of CMFT. The lack of resources, health care infrastructure, and surgical personnel in these areas result in subpar treatment and poor patient outcomes, contributing to the high mortality and morbidity rates among war victims. The importance of a multidisciplinary approach to CMFT management cannot be overstated, but current obstacles, such as a lack of access to proper medical care and rehabilitation services, impede the development of effective treatments. CMFT treatment is complex and prohibitively expensive for war-torn nations to afford, necessitating international intervention to provide life-saving surgical procedures for those suffering from CMFT in conflict zones. Despite efforts to improve CMFT treatments in war-torn countries, more must be done to improve treatment outcomes. Data collection and research must also be improved in order to develop effective evidence-based treatment methods.

RESUMO

The most common malignant tumors of the uterus are endometrioid adenocarcinomas (EA). Their prognosis depends on the qualitative characteristics of the neoplastic cells and their stroma. The neovascularization of EA tissues and level of microvascular density (MVD) influence tumor progression. Our study aims to establish the relationship between MVD in EA tissue and the histological and immunohistochemical features of tumors. Materials and methods: The authors studied 30 cases of endometrial ЕА and compared their histological and immunohistochemical characteristics with the MVD of tumor tissues. Results: Our study indicated that MVD in EA tissue depends on the grade of the tumors and their FIGO stage. Increased MVD was correlated with a depression of E-cadherin and PR expression and enhanced expression of VEGF and Ki-67. MVD enhancement during VEGF overexpression is a manifestation of the functional activity of these proteins. The increase in MVD was accompanied by more frequent metastasis of the EA to the lymph nodes. Conclusion: EA progression is accompanied by qualitative and quantitative variations of parenchymal and stromal patterns of tumors. Dedifferentiation of EA leads to overexpression of VEGF, which becomes diffuse in tumors cells, resulting in an increase of adenocarcinomas' MVD and their metastatic potential. Correlations between histological and immunohistochemical features of EAs indicate the synchronicity of the occurrence and progression of morphological and immunological anaplasia, which can be used in predicting the course of the disease.

RESUMO

With increasing prevalence and an expected rise in disease burden, cancer is a cause of concern for African healthcare. The cancer burden in Africa is expected to rise to 2.1 million new cases per year and 1.4 million deaths annually by the year 2040. Even though efforts are being made to improve the standard of oncology service delivery in Africa, the current state of cancer care is not yet on par with the rise in the cancer burden. Cutting-edge technologies and innovations are being developed across the globe to augment the battle against cancer; however, many of them are beyond the reach of African countries. Modern oncology innovations targeted to ward Africa would be promising to address the high cancer mortality rates. The innovations should be cost-effective and widely accessible to tackle the rapidly rising mortality rate on the African continent. Though it may seem promising, a multidisciplinary approach is required to overcome the challenges associated with the development and implementation of modern oncology innovations in Africa.

RESUMO

The need for improved palliative care in developing countries is great. Of 58 million people who die every year, 45 million die in developing countries. An estimated 60% (27 million) of these people in poor nations would benefit from palliative care, and this number is growing as chronic diseases such as cancer rise rapidly. Yet a combination of highly restrictive policies on opioid prescription and a lack of awareness within the medical profession conspire to deprive patients of palliative care. Human rights advocates argue that this neglect is a breach of human rights that is tantamount to torture. This editorial explores the neuropalliative approach and addresses the current state of neuropalliative care in developing countries.
