Antipsychotic medications, while crucial in managing severe psychiatric disorders such as schizophrenia and bipolar disorder, are frequently associated with extrapyramidal symptoms (EPS) and tardive dyskinesia (TD). TD, characterized by repetitive, involuntary movements, especially of the face and limbs, poses a substantial clinical challenge due to its often irreversible nature. Conventional management strategies, including dose reduction and switching to atypical antipsychotics, frequently offer limited success, prompting exploration of alternative therapies.

Article Synopsis
  • A qualitative analysis was conducted in August 2023 comparing ChatGPT-3.5 and Bard (Google Gemini) on their accuracy in answering 12 commonly asked pregnancy questions, graded against established medical guidelines.
  • Bard outperformed ChatGPT-3.5, with 83% of its responses deemed "acceptable" compared to 58% for ChatGPT-3.5; however, both models exhibited significant issues with reference verification.
  • Despite a slight improvement in ChatGPT-3.5’s performance over time, both models require further scrutiny before being considered trustworthy sources for pregnancy information.

Liver cancer, primarily hepatocellular carcinoma (HCC), is the second leading cause of cancer-related deaths globally. It is typically characterized by rapid progression, poor prognosis, and high mortality rates. Given these challenges, the search for molecular targets aiding early diagnosis and targeted therapy remains imperative.

Esophageal carcinoma (EC) is among the most common causes of cancer-related deaths worldwide. Even with the improvement of multidisciplinary treatment modalities, advanced unresectable EC patients had limited systemic therapeutic options for an extended period. Recently, immune checkpoint inhibitors (ICIs) have been introduced to advanced EC management in both first-line and second-line options, as well as in postoperative settings in resectable EC after preoperative chemoradiation.

This paper shines a light on the exciting progress being made in using immunotherapy to treat advanced gastroesophageal cancers. The positive results from trials using drugs like Pembrolizumab and Nivolumab are certainly encouraging and open new possibilities for treating this challenging disease. However, it is clear that we still have a lot to learn about how to predict which patients will benefit most from these treatments.

HCC, the most prevalent form of primary liver cancer, presents a substantial global health challenge due to its high mortality and limited therapeutic options. This review delves into the potential of cancer vaccines as a novel therapeutic avenue for HCC. We examine the various categories of cancer vaccines, including peptide-based, dendritic cell-based, viral vector-based, DNA, and mRNA vaccines, and their potential application in HCC management.

Purpose: The azygos system of veins has many anatomical variations that can impact mediastinal and vascular interventions. While radiological reports on these are of great clinical value, this study is among the first to present a high-quality cadaveric dissection of a rare anatomical variant to supplement previously published radiologic studies. The azygos venous system consists of the azygos vein (AV), hemiazygos vein (HAV), and the accessory hemiazygos vein (AHAV), which develop from the last portion of the posterior cardinal veins.

Leptomeningeal metastasis (LM), also known as leptomeningeal carcinomatosis (LC), is a devastating complication of metastatic cancer that occurs when neoplastic cells invade the meningeal space. Diagnosis of LM remains challenging given the heterogeneous signs and symptoms at presentation and requires thorough neurological examination, cerebrospinal fluid (CSF) analysis, and MRI of the brain and spine with gadolinium. Detecting neoplastic cells in the CSF is the gold standard for diagnosing leptomeningeal metastases; however, it has low sensitivity and may require multiple CSF samples.

Patients with cancer are now living longer than ever before due to the growth and expansion of highly effective antineoplastic therapies. Many of these patients face additional health challenges, of which cardiovascular disease (CVD) is the leading contributor to morbidity and mortality. CVD and cancer share common biological mechanisms and risk factors, including lipid abnormalities.

The pathophysiology of hypertension and cancer are intertwined. Hypertension has been associated with an increased likelihood of developing certain cancers and with higher cancer-related mortality. Moreover, various anticancer therapies have been reported to cause new elevated blood pressure or worsening of previously well-controlled hypertension.

Statin-associated myopathy comprises of a spectrum of conditions ranging from benign myalgias to statin-induced immune-mediated necrotizing myopathy. Statin-induced immune-mediated necrotizing myopathy is an autoimmune condition wherein there is a destruction of normal skeletal muscular architecture that can be severely debilitating if not recognized promptly. Given its rarity, management is a challenge.

Spontaneous tumor lysis syndrome (TLS) is a rare condition in solid tumors, particularly in endometrial carcinoma. Spontaneous TLS occurs without the use of cytotoxic therapy but is observed particularly in hematologic malignancies. Given the high morbidity and mortality associated with spontaneous TLS, it is crucial to identify and treat it promptly.

Introduction: Bortezomib is a proteasome inhibitor used in the treatment of multiple myeloma, Waldenström's macroglobulinemia, mantle cell lymphoma. The most reported adverse effects include fatigue, thrombocytopenia, gastrointestinal symptoms, and peripheral neuropathy, which mostly manifests as sensory neuropathic symptoms. We present a case of a patient who experienced motor neuropathy after initiating treatment with bortezomib.

Oxaliplatin, a platinum-based chemotherapy agent, is commonly used in the treatment of various malignancies. Common adverse effects involve neurological, hematological, gastrointestinal system, and hypersensitivity, and rarely ocular changes have also been reported. We describe the case of a 71-year-old male, who developed reversible ocular toxicity after receiving oxaliplatin for treatment for pancreatic cancer.
