RESUMO

Parkinson disease (PD), a prevalent neurodegenerative ailment in the elderly, relies mainly on pharmacotherapy, yet deep brain stimulation (DBS) emerges as a vital remedy for refractory cases. This study performs a bibliometric analysis on DBS in PD, delving into research trends and study impact to offer comprehensive insights for researchers, clinicians, and policymakers, illuminating the current state and evolutionary trajectory of research in this domain. A systematic search on March 13, 2023, in the Scopus database utilized keywords like "Parkinson disease," "PD," "Parkinsonism," "Deep brain stimulation," and "DBS." The top 1000 highly cited publications on DBS in PD underwent scientometric analysis via VOS Viewer and R Studio's Bibliometrix package, covering publication characteristics, co-authorship, keyword co-occurrence, thematic clustering, and trend topics. The bibliometric analysis spanned 1984 to 2021, involving 1000 cited articles from 202 sources. The average number of citations per document were 140.9, with 31,854 references. "Movement Disorders" led in publications (n = 98), followed by "Brain" (n = 78) and "Neurology" (n = 65). The University of Oxford featured prominently. Thematic keyword clustering identified 9 core research areas, such as neuropsychological function and motor circuit electrophysiology. The shift from historical neurosurgical procedures to contemporary focuses like "beta oscillations" and "neuroethics" was evident. The bibliometric analysis emphasizes UK and US dominance, outlining 9 key research areas pivotal for reshaping Parkinson treatment. A discernible shift from invasive neurosurgery to DBS is observed. The call for personalized DBS, integration with NIBS, and exploration of innovative avenues marks the trajectory for future research.

RESUMO

This case highlights the importance of considering tuberculosis as an underlying cause of gastrointestinal amyloidosis, even in patients previously treated for the infection. Clinicians should maintain a high index of suspicion for atypical presentations of amyloidosis, especially in individuals with chronic inflammation, enabling early diagnosis and tailored management for improved patient outcomes. Abstract: Gastrointestinal amyloidosis is a rare condition often associated with chronic inflammation. We present a unique case of a 50-year-old female with a history of miliary tuberculosis who developed gastrointestinal amyloidosis. The patient exhibited chronic loose stools, weight loss, abdominal pain, and urinary incontinence symptoms. Diagnostic workup revealed characteristic findings of amyloidosis on biopsy. Despite treatment for tuberculosis, her symptoms persisted, highlighting the challenging nature of managing this condition. This case underscores the importance of considering tuberculosis as a potential cause of secondary amyloidosis in patients with ongoing symptoms of inflammation and infection. Early recognition and tailored management are crucial in optimizing patient outcomes.

RESUMO

Key Clinical Message: This case emphasizes the significance of COVID-19 in pediatric patients presenting with unusual hepatic manifestations, urging clinicians to broaden their diagnostic lens. The unexpected elevation of SARS-CoV-2 antibodies and the effective use of N-acetyl cysteine highlight the importance of adaptability in treatment strategies. Abstract: This case report presents a unique manifestation of severe hepatic involvement in a 4-year-old girl with thalassemia minor and COVID-19. Despite the absence of prominent respiratory symptoms, the patient exhibited jaundice, elevated liver enzymes, and coagulopathy. Initial suspicion of viral hepatitis was replaced by the discovery of significantly elevated SARS-CoV-2 antibodies. A multidisciplinary approach, including gastroenterology consultation and an extensive workup, was pivotal in ruling out alternative etiologies. Unconventional use of N-acetyl cysteine contributed to clinical improvement, highlighting the need for adaptable treatment strategies. This case underscores the importance of heightened awareness in recognizing atypical presentations of COVID-19 in pediatric patients, especially those with underlying health conditions. Further exploration into nuanced manifestations and treatment approaches is warranted for comprehensive clinical management.

RESUMO

OBJECTIVE: Evaluate the safety and efficacy of zavegepant (BHV-3500), a recently approved nasal spray containing a third-generation calcitonin gene-related peptide receptor antagonist, for treating acute migraine attacks. METHODS: A comprehensive search was conducted across various databases up to 06/26/2023 to identify relevant randomized clinical trials (RCTs) on zavegepant's efficacy and safety in treatment of acute migraine attacks. Primary outcome: freedom from pain at 2 hours postdose. Safety outcomes were evaluated based on adverse events (AEs), with zavegepant 10 mg and placebo groups compared for incidence of AEs. RESULTS: Two RCTs, involving 2061 participants (1014 receiving zavegepant and 1047 receiving placebo), were quantitatively analyzed. An additional trial was included for qualitative synthesis. Zavegepant 10 mg exhibited a significantly higher likelihood of achieving freedom from pain at 2 hours postdose compared with the placebo group (risk ratio [RR] 1.54, 95% confidence interval [CI] 1.28 to 1.84). It also showed superior relief from the most bothersome symptoms at 2 hours postdose compared with placebo (RR 1.26, 95% CI 1.13 to 1.42). However, the zavegepant 10 mg group experienced a higher incidence of AEs compared with placebo (RR 1.78, 95% CI 1.5 to 2.12), with dysgeusia being the most reported AE (RR 4.18, 95% CI 3.05 to 5.72). CONCLUSION: Zavegepant 10 mg is more effective than placebo in treating acute migraine attacks, providing compelling evidence of its efficacy in relieving migraine pain and most bothersome associated symptoms. Further trials are necessary to confirm its efficacy, tolerability, and safety in diverse clinic-based settings with varied patient populations.

RESUMO

Conventional therapeutic techniques for brain tumours have limitations and side effects, necessitating the need for alternative treatment options. MRI-monitored therapeutic hydrogel systems show potential as a non-surgical approach for brain tumour treatment. Hydrogels have unique physical and chemical properties that make them promising for brain tumour treatment, including the ability to encapsulate therapeutic agents, provide sustained and controlled drug release, and overcome the blood-brain barrier for better penetration. By combining hydrogel systems with MRI techniques, it is possible to develop therapeutic approaches that provide real-time monitoring and controlled release of therapeutic agents. Surgical resection remains important, but there is a growing need for alternative approaches that can complement or replace traditional methods. The objective of this comprehensive narrative review is to evaluate the potential of MRI-monitored therapeutic hydrogel systems in non-surgical brain tumour treatment.

RESUMO

INTRODUCTION: This case study reports on a suicide attempt involving indoxacarb and vitamin C. Indoxacarb is a neurotoxic insecticide used in agriculture and as a flea controller in pets. Cotton, vegetables, and fruits are treated with indoxacarb, an insecticide that can be applied both indoors and outdoors. It causes skin allergies, methemoglobinemia, and hemolytic anemia. It is also attributed to allergic reactions through ingestion, inhalation, physical contact, and translaminar action. This case report highlights use of vitamin C in methemoglobinemia caused by indoxacarb poisoning. Indoxacarb poisoning has the potential to be extremely serious and even lethal. In this instance, the patient initially had no symptoms after ingesting a substance containing indoxacarb in an attempt at suicide. However, further tests revealed methemoglobinemia and low oxygen levels. CASE PRESENTATION: A 28-year-old south-east Asian female patient ingested an insecticide containing 5.25% novaluron, 4.5% indoxacarb, and 25% thiamethoxam, and reported that she noticed muddy brown urine but presented with no active signs or symptoms of poisoning. Upon examination, the patient was fully conscious, alert, and hemodynamically stable, but had an oxygen saturation of 84%. Gastric lavage was performed, and blood investigations revealed a muddy-brown-colored blood sample and methemoglobin levels of 12%. The patient was treated with high-dose vitamin C and showed significant improvement, with a drop in methemoglobin levels to 1.2% and an increase in oxygen saturation to 97%. DISCUSSION: Indoxacarb poisoning can cause severe methemoglobinemia. Vitamin C may be a useful treatment option for methemoglobinemia caused by indoxacarb, particularly in cases in which traditional treatment with methylene blue is contraindicated or not tolerated. Hence high doses of ascorbic acid, that is, vitamin C, were administered to the patient, which lowered their methemoglobin levels and improved oxygen levels without much safety concerns. CONCLUSION: This example emphasizes the significance of early indoxacarb poisoning detection and treatment as well as the possible advantages of utilizing ascorbic acid in the management of methemoglobinemia, and highlights the use of vitamin C in the treatment of methemoglobinemia caused by indoxacarb poisoning. Therefore, it is important for healthcare professionals to be aware of the potential for indoxacarb to cause methemoglobinemia and to consider vitamin C as a treatment option.

RESUMO

Diabetic foot ulcer is a debilitating complication of long-standing diabetes mellitus. Patients lose their earning potential, face repeated hospitalizations, and are forced to bear heavy treatment costs. This places an enormous financial burden on the patients and their families. This study seeks to ascertain the out-of-pocket expenditure among these patients and correlate it with their risk factor profile. In this hospital-based cross-sectional study, a total of 154 patients with diabetic foot ulcers or amputations have been studied with an elaborate patient questionnaire and relevant clinical examinations. The costs incurred and the risk factors of the patients were analyzed for statistical association. The median total annual out-of-pocket expenditure for the management of diabetic foot ulcers among the study participants was found to be ₹29 775 (₹9650-₹81 120) ($378.14 [$122.56-$1030.22]). Out of the total expenditure, 58.49% went towards direct medical costs, 5.64% towards direct non-medical costs, and 35.88% for indirect costs. Medications, ulcer dressing and periodic debridement have accounted for 79.26% of direct medical costs. Transportation (61.37%) and patient's loss of income (89.45%) account for the major costs under the direct non-medical and indirect cost categories, respectively. A high ulcer grade and area, long ulcer duration, and past history of ulcers have higher expenditure. Patients seeking treatment from private establishments and those engaged in professional/skilled occupations have higher expenses. Adequate dressing of foot ulcers and proper footwear are associated with lower treatment expenditure. 68.8% of the participants have faced catastrophic expenditure due to treatment costs of diabetic foot ulcers. Adequate glycaemic control and proper foot care are necessary. Patients must seek medical care at the earliest in case of foot ulceration. Clinicians must provide proper wound care, institute effective antibiotics, and manage the complications. Government and insurance schemes are required to alleviate the patients' financial burden.

RESUMO

BACKGROUND: Testicular tumors have many different manifestations. The majority of these cases are presented as an incidental finding during hydrocelectomy. Malignant mesotheliomas are uncommon tumours that can arise from the coelomic epithelium of the pleura, peritoneum, pericardium, and tunica vaginalis. CASE PRESENTATION: We present a 51-year-old South Asian (Indian) male patient with a rare case of mesothelioma, presenting with right hydrocele, to whom a right hydrocelectomy was performed. Any history of trauma or asbestos exposure was not present. Histopathological and immunohistochemistry reports revealed a malignant mesothelioma of tunica vaginalis. There was no invasion of the tumour to the epididymis and spermatic cord. Imaging studies showed no signs of metastasis. 1 month later, a high inguinal orchidectomy was performed. The patient underwent adjuvant chemotherapy thereafter and is still on follow-up. CONCLUSION: Although hydrocele is common, detailed evaluation is mandatory to rule out certain rare tumours-testicular and paratesticular variants.

RESUMO

The chromosomal band 17q12 is characterized by a high density of genes and is bordered by segmental duplications, the structural arrangement of which increases the susceptibility of the region to deletions and duplications. Duplication of 17q12 is a rare genetic condition associated with variable characteristics from clinically asymptomatic to intellectual disabilities, seizures, and behavioral problems. The variability in phenotype is primarily due to variable expressivity and incomplete penetrance. Diagnosis is mostly established by chromosomal microarray. Treatment involves a multidisciplinary approach. We present a case of a 43-year-old female who initially presented with hyperphagia and was eventually diagnosed with bulimia nervosa, anxiety, mood disorder, and personality disorder. Additional research is required to better understand the impact of 17q12 duplication syndrome on the development of bulimia nervosa since its pathogenesis has not been adequately described in the current literature.

RESUMO

Introduction and importance: Hyper-IgE syndrome (HIES), also known as Job syndrome, is a rare primary immunodeficiency disorder characterized by elevated serum IgE levels, recurrent infections, and various clinical features. Early diagnosis, prompt management of infections, and supportive care are essential in improving outcomes for individuals with HIES. Genetic testing, including STAT3 gene sequencing, plays a crucial role in confirming the diagnosis. Further research is needed to enhance our understanding of HIES and develop targeted therapies to improve the quality of life for affected individuals. Case presentation: This case report presents the clinical features and management of a 37-year-old male with HIES, diagnosed at the age of 2 due to recurrent cold abscesses caused by Staphylococcal infections. Clinical discussion: The patient exhibited typical symptoms of HIES, including recurrent eczema, frequent bacterial infections, mucocutaneous candidiasis, and various physical abnormalities. Diagnostic markers such as elevated IgE levels and eosinophilia supported the HIES diagnosis, which was further confirmed by the identification of a STAT3 gene mutation. Treatment primarily involved supportive measures and antibiotics for infections. The patient's blood test results and imaging findings revealed abnormalities such as low red blood cell count, elevated erythrocyte sedimentation rate, and pulmonary nodules. Conclusion: This case report highlights the importance of early diagnosis, prompt management of infections, and the need for ongoing research to improve our understanding and treatment of HIES.

RESUMO

Key Clinical Message: Spinal muscular atrophy (SMA) is a growing clinical concern, necessitating higher awareness and early detection. This case study focuses on the difficulties and advances in detecting and treating SMA. It emphasizes the value of early detection, interdisciplinary care, genetic testing, and novel therapeutics in terms of improving outcomes. Abstract: Spinal muscular atrophy type 1 (SMA Type 1) is a rare genetic neuromuscular disease characterized by muscle atrophy and weakness. This case report presents the fatal outcome of a 1-year-old girl with delayed diagnosis of SMA Type 1. The child exhibited symptoms of muscle weakness and respiratory distress, which were initially overlooked. Despite a thorough examination and diagnostic tests, including genetic analysis, SMA Type 1 with a homozygous deletion in the survival motor neuron 1 (SMN1) gene was confirmed. The child received supportive measures and physiotherapy but experienced a progressive deterioration of her condition and eventually succumbed to the disease. This case underscores the challenges of diagnosing SMA and highlights the importance of early identification for appropriate management. Improved awareness, diagnostic protocols, and access to treatment options, including pharmacological drugs and gene therapy, are essential to improve outcomes for SMA Type 1 patients, particularly in resource-limited settings. Early detection through newborn screening programs and timely intervention can significantly impact the prognosis and life expectancy of SMA Type 1 children, emphasizing the need for continued research and clinical trials to establish a definitive cure.

RESUMO

Key Clinical Message: Tuberculosis (TB) of the odontoid process is a rare but potentially, a debilitating condition. Surgical intervention, in the form of stabilizing the spine and decompressing the spinal cord, offers a tailored approach to managing this condition effectively and improving prognosis. Abstract: Odontoid process tuberculosis (TB) is a rare condition that can cause spinal instability and neurological complications. Diagnosis of odontoid process TB is difficult and requires a combination of clinical, radiographic, and histopathological examinations. This report describes the treatment of a 46-year-old female with quadriparesis and intermittent fever. Radiological findings showed TB of the odontoid process with atlanto-axial dislocation causing compressive myelopathy. She underwent C1-C3 decompressive laminectomy and stabilization from C1 to C5. GeneXpert for TB was positive and she was started on anti-tuberculous medications. She regained power gradually and at 1 year follow-up she was ambulant without any support. The C1-C5 lateral mass screw and C1-C3 decompressive laminectomy approach, as highlighted in this case, offers an effective solution, enhancing patient quality of life, and preventing disease progression.

RESUMO

Background and aims: The World Health Organization has recently declared the frequent outbreaks of diphtheria in Nigeria as a public health concern. Although vaccination efforts have been successful in Nigeria, unfortunately, the recent 2023 outbreak in Nigeria has been nothing short of distressing. Of course, cases of diphtheria incidence are under-reported in Nigeria. This present article aims to proffer a possible multifaceted approach to tackle outbreaks of diphtheria in Nigeria and improve immunization rates against the disease among the Nigerian population. Methods: In writing this study, literature search was done about diphtheria in Nigeria using the following keywords: "diphtheria, prevalence, vaccination, efforts, challenges, and Nigeria" on PubMed, Web of Science, Google Scholar, and ResearchGate within 10 years. Result: This study found that an estimated seven million people remain unvaccinated and are at risk for infection in the country, especially people living in the Northern part of the country. Between the June 30 and August 31, 2023, Nigeria recorded an unusual increase in the number of confirmed cases of diphtheria, where a total of 5898 suspected cases were reported from 59 local government areas in 11 states across Nigeria. The majority (99.4%) of suspected cases of the disease were reported from six states: Kano (1816), Katsina (234), Yobe (158), Bauchi (79), Kaduna (45), and Borno (33). Conclusion: If Nigeria is to emerge beyond these frequent epidemics of diphtheria, the Nigerian government must work on tackling this issue on multiple fronts simultaneously, that is, at the national and international levels, as we believe that these levels would give a holistic way to unmask diphtheria in Nigeria.

RESUMO

Circulating tumor cells (CTCs) are cancer cells that detach from the primary tumor, enter the bloodstream or body fluids, and spread to other body parts, leading to metastasis. Their presence and characteristics have been linked to cancer progression and poor prognosis in different types of cancer. Analyzing CTCs can offer valuable information about tumors' genetic and molecular diversity, which is crucial for personalized therapy. Epithelial-mesenchymal transition (EMT) and the reverse process, mesenchymal-epithelial transition (MET), play a significant role in generating and disseminating CTCs. Certain proteins, such as EpCAM, vimentin, CD44, and TGM2, are vital in regulating EMT and MET and could be potential targets for therapies to prevent metastasis and serve as detection markers. Several devices, methods, and protocols have been developed for detecting CTCs with various applications. CTCs interact with different components of the tumor microenvironment. The interactions between CTCs and tumor-associated macrophages promote local inflammation and allow the cancer cells to evade the immune system, facilitating their attachment and invasion of distant metastatic sites. Consequently, targeting and eliminating CTCs hold promise in preventing metastasis and improving patient outcomes. Various approaches are being explored to reduce the volume of CTCs. By investigating and discussing targeted therapies, new insights can be gained into their potential effectiveness in inhibiting the spread of CTCs and thereby reducing metastasis. The development of such treatments offers great potential for enhancing patient outcomes and halting disease progression.

RESUMO

INTRODUCTION AND IMPORTANCE: D-wave (Direct waves) are Motor Evoked Potentials (MEPs) generated by a single transcranial stimulation and captured by attaching an epidural recording electrode caudal to the vulnerable area. Intraoperative neurophysiologic monitoring (IONM) is widely used in neurosurgery to recognize important neurological structures but can be challenging in the pediatric population due to incomplete neural development. CASE PRESENTATION: Case 1: A 48-year-old female presented to the outpatient department with complaints of difficulty walking for the past six months, numbness and weakness in bilateral lower limbs with recurrent falls for the past 1 month. Case 2: A 12-year-old boy presented to the emergency room with a history of inability to use both upper and lower limbs on the right side with tremulousness. CLINICAL DISCUSSION: Magnetic resonance imaging (MRI) Spine in the first case revealed a D9-D10 calcified meningioma with significant spinal cord compression. In the second case, MRI Spine showed C1-C2 Intramedullary Space Occupying Lesion (SOL) and was planned for C1-C2 laminectomy with midline myelotomy. The first case was planned for microsurgical excision of the lesion under IONM guidance. The procedure went smoothly. Microsurgical gross total resection (GTR) of the intramedullary SOL under IONM Guidance was done for the second case. Postoperatively, the first patient showed no neurological compromise or complications. In the second case, following surgery, the child recovered gradually from surgery. CONCLUSION: This case series demonstrates the successful surgical management of two cases of spinal cord tumors through an IONM-guided surgery and the effective use of D waves in such challenging cases.
