Primary Intracranial Malignant Melanoma, Ummey Hani, Dr Saqib Kamran Bakhshi, Muhammad Shahzad Shamim

Section of Neurosurgery

Primary intracranial malignant melanoma (PIMM) are rare brain tumours; more infrequent than melanomas metastasizing to the brain or those extending to the brain from adjacent structures such as the orbit. Complete surgical excision with adjuvant chemotherapy and radiation remains the mainstay of treatment. Herein, we have reviewed the literature to find the treatment modalities for PIMMs that can lead to longer overall survivals and better patient outcomes.

Immediate Changes In Hemodynamics And Gas Exchange After Initiation Of Noninvasive Ventilation In Cardiac Surgical Patients, Mohammad Hamid, Mohammad Irfan Akhtar, Saba Ahmed

Department of Anaesthesia

Introduction: Cardiac surgery is associated with pulmonary dysfunction and complications such as prolonged intubation and reintubation. Bilevel positive airway pressure (BiPAP) machine has been used in the clinical settings to improve oxygenation, reduce work of breathing, and avoid reintubation. The effect of BiPAP on cardiovascular parameters is not well established, and very few studies have targeted hemodynamic changes. The aim of the study was to assess the immediate effect of BiPAP on respiratory and hemodynamic parameters in post-cardiac surgery patients.
Materials and methods: This quasi-experimental study was done on 33 adult cardiac surgery patients. Ethical review committee approval was sought …

Meeting The Educational Needs Of An Increasingly Diverse Surgical Workforce, Minerva Angelica Romero Arenas

School of Medicine Publications

To the Editor Yeo et al¹ evaluated factors associated with American Board of Surgery (ABS) examination pass rates in a cohort of categorical surgical residents from the internship (2007) to eligibility/certification. They found that first-time ABS pass rate was associated with nonmodifiable factors, such as nonwhite race/ethnicity, sex (women), and having children.¹ Additionally, Hispanic residents were less likely to attempt the ABS examinations at all. We must place these findings in the context of diversity in surgery, or rather, the lack thereof. The cohort included only 55 Hispanic residents, most of whom did pass the ABS examinations (n …

The Great Imitator Strikes Again: A Case Of A Lupus Flare-Up Presenting Like An Acute Abdomen, Emmanouil Kiriakopoulos, Vanessa Perez, Robyn Hoelle

HCA Healthcare Journal of Medicine

Systemic lupus erythematosus (SLE) is an autoimmune disease affecting all age groups and can manifest in various forms, often making the initial or successive presentations difficult to diagnose. Peritonitis secondary to lupus is a rare manifestation of this disease and the prevalence is said to be much lower in children. We present a case report of an adolescent male with a known history of lupus who presented to the emergency department with a clinical picture consistent with an acute surgical abdomen and underwent an appendectomy. Subsequent workup identified the culprit as a lupus-related peritonitis requiring corticosteroids for resolution.
