RESUMO

Introduction: Paediatric bacterial meningitis (PBM) represents a major contributor to childhood morbidity and mortality globally, with heightened susceptibility in low- and middle-income nations where antimicrobial resistance (AMR) is highly prevalent. Pakistan exemplifies this setting, with widespread antibiotic overuse driving AMR expansion. Thus, expediting PBM diagnosis and targeted antibiotic therapy is imperative yet challenged by the dynamic local epidemiology. This study aimed to delineate the recent bacterial etiologies and AMR profiles of PBM from a major Pakistani diagnostics laboratory to inform empirical treatment. Materials and methods: This prospective observational investigation evaluated PBM epidemiology in patients under 18 years old admitted to the study hospital. Standard cerebrospinal fluid analysis identified bacterial pathogens and antibiotic susceptibility patterns. Results: Among 171 PBM cases, 152 (88.9%) had bacterial isolates confirmed via culture. The cohort was 42.7% male with a mean age of 3 months. The most prevalent pathogens among infants younger than 3 months were Escherichia coli, Enterococcus faecium, and Staphylococcus epidermidis, contrasting with S. epidermidis, Streptococcus pneumoniae, and Staphylococcus hominis predominating in older children. Staphylococcal isolates exhibited considerable penicillin and erythromycin resistance but maintained vancomycin and linezolid susceptibility. Other resistance patterns varied. Conclusion: These findings highlight the pressing threat of paediatric AMR in Pakistan, underscoring the need for vigilant AMR surveillance and judicious antimicrobial use. This study provides a reference to current PBM epidemiology to guide context-specific empirical therapy.

RESUMO

Key Clinical Message: Scalp metastasis from atypical meningioma, though rare, underscores the importance of meticulous surgical techniques to prevent tumor cell implantation. Early detection and comprehensive management, including surgery and adjuvant therapy, are crucial for optimal outcomes. Abstract: Meningiomas are tumors of the meninges that originate in the arachnoid layer from arachnoid cap cells. Atypical meningiomas, classified as WHO grade 2 tumors, tend to metastasize and recur if not surgically managed properly. Scalp metastasis is a rare occurrence that presents as a subcutaneous elevation. A 33-year-old patient presented with a complaint of a constant, dull pressure headache persisting for the past 12 months, exacerbated by exertion, along with seizures and neuropsychiatric symptoms. The patient had no significant medical history but had undergone surgery 4 years ago for a WHO grade 2 meningioma. The current brain MRI revealed a dural tail sign, along with masses on both the left and right sides of the frontal lobe, extending to involve the skin on the forehead and scalp. The patient underwent surgical resection and adjuvant radiation therapy. At the 12-month follow-up, no neurological deterioration or tumor recurrence was observed. A literature review on scalp metastasis in patients with atypical meningioma was also conducted, including eight articles published up to September 2023. The mechanism of metastasis development appears to be consistent in all eight reported cases, involving the implantation of tumor cells during resection. Therefore, there is a critical need for meticulous intra- and post-operative surgical techniques to prevent such implantation.

RESUMO

Intricate fields have always posed a challenge for the healthcare department all over the world, particularly in developing countries. This article elaborates on the history of neurosurgery in a developing country like Pakistan. In addition, it provides a summary of a roadmap that a young healthcare practitioner, who inspires to become a respectable neurosurgeon may need. After Pakistan gained its independence, Dr. Omer Wali Jooma became the first healthcare practitioner who planted the seed of an official department of Neurosurgery in Jinnah hospital, Karachi. Various challenges include the absence of a non-standardized curriculum, a non-updated syllabus, severe deficiency of neurosurgeons in a country facing massive growth spurt, lack of facilities for a young trainee etc. These factors contribute to the bleeding of the department from various sites and the wounds needs to be addressed and stitched as soon as possible to make the department successful.

RESUMO

Chronic subdural hematomas are typically observed in elderly patients receiving antithrombotic and/or anticoagulant therapy. In contrast, acute subdural and extradural hematomas are often observed in young people with traumatic brain injury. The coexistence of ipsilateral chronic subdural and extradural hematomas is rare. Depending on the Glasgow Coma Scale and neuroimaging findings, early surgical intervention is mandatory, as seen in our patient. Early surgical evacuation of a traumatic extradural and chronic subdural hematoma should be done. Also, antithrombotic drug use can lead to chronic subdural hematoma.

RESUMO

BACKGROUND: Asia has a marked shortage of neurosurgical care, with approximately 2.5 million critical cases left untreated. The Young Neurosurgeons Forum of the World Federation of Neurosurgical Societies surveyed Asian neurosurgeons to identify research, education, and practice. METHODS: A cross-sectional study using a pilot-tested e-survey was circulated to the Asian neurosurgical community from April to November 2018. Descriptive statistics were used to summarize variables pertaining to demographics and neurosurgical practices. The chi-square test was used to explore the relationship between World Bank income level and variables on neurosurgical practices. RESULTS: A total of 242 responses were analyzed. Respondents were mostly from the low- and middle-income countries (70%). Most represented institutions were teaching hospitals (53%). More than 50% of the hospitals had between 25and 50 neurosurgical beds. Access to an operating microscope (P = 0.038) or image guidance system (P = 0.001) appeared to increase in correlation to a higher World Bank income level. Limited opportunities for conducting research (56%) and hands-on operating opportunities (45%) were leading challenges in daily academic practice. The leading challenges were limited numbers of intensive care unit beds (51%), inadequate or absent insurance coverage (45%), and lack of organized perihospital care (43%). Inadequate insurance coverage decreased with increasing World Bank income levels (P < 0.001). Organized perihospital care (P = 0.001), regular magnetic resonance imaging access (P = 0.032), and equipment necessary for microsurgery (P = 0.007) increased with higher World Bank income levels. CONCLUSIONS: Improving neurosurgical care hinges on regional and international collaboration and national policies to ensure universal access to essential neurosurgical care.

RESUMO

Due to change in lifestyle and food habits, people are more at risk of diet-related diseases and cancers. It is also established that dietary modifications significantly reduce the risk of diseases. Nutrigenomics is relatively fresh discipline, but possess an enormous potential that can apply for prevention and management of certain carcinomas and diseases. This review enables us to generate useful information for scientists and health professionals regarding the role of Nutrigenomics in the prevention of diet and lifestyle-related diseases like cancer. It influences health conditions of individuals and susceptibility of disease by defining the metabolic response and gene expression. Epigenetic modifications can perform a significant role in disease occurrence and pathogenesis. DNA methylation and chromatin remodeling are the most common epigenetic mechanisms. Omega 3 fatty acids are the best example of nutrients and gene interaction not involving DNA methylation while certain bioactive food compounds have a proven role in cancer prevention through an epigenetic mechanism. Dietary polyphenols substantially take part in prevention of oral, breast, skin, esophageal, colorectal, prostate, pancreatic and lung cancers. Moreover, minerals and vitamins involve regulatory processes. Zinc, Selenium and folate involve in DNA repairing process have anticancer properties. Consumption of multivitamins prevents methylation of cancer cells.
