RESUMO

BACKGROUND: Medical students often face challenges in choosing a career path due to limited exposure to specialized fields like neurosurgery. Understanding their perceptions and experiences is crucial in addressing the gaps in neurosurgical education and inspiring future neurosurgeons. METHODS: A cross-sectional study was conducted involving 461 medical students, utilizing convenience sampling. Data collection employed a validated, self-administered tool. Statistical analysis in SPSS Version 25 included t-tests and chi-square tests, comparing scores based on age, gender, year of study, and exposure to the formal neurosurgical rotations in their institute. Significance value was set at P < 0.05. RESULTS: In the study of 461 medical students, 79.8% identified with the 19-23 age group, and 63.8% affirmed neurosurgery exposure. Medical students' perceptions included: 167 (36.3%) students found neurosurgery teaching sufficient; 164 (35.6%) disagreed that obtaining neurosurgical history is difficult; 224 (48.6%) agreed on neurosurgical disease complexity; and 250 (54.2%) found these diseases challenging and interesting. A majority of 183 (39.7%) respondents agreed that neurosurgical diseases had poor outcomes. Regarding training for neurosurgical surgery, 205 (44.5%) participants strongly agreed on its length, and 215 (46.7%) consented to extensive operating hours. However, 167 (36.3%) strongly disagreed about the ample job prospects in Pakistan. CONCLUSIONS: Enhancing neurosurgery education with quality, consistency, and adaptability is essential to bridge gaps and inspire future neurosurgeons. These findings guide improvements in educational programs, preparing a skilled workforce to meet evolving health-care demands.

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

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.
