Non-Hodgkin’s lymphoma (NHL) represents a diverse group of blood cancers originating in lymphatic tissues. While many patients respond positively to initial treatment regimens, some experience relapse or refractory forms of the disease. Relapse refers to the return of cancer after a period of remission, whereas refractory lymphoma indicates the disease’s resistance to treatment. These two

Regional anesthesia plays a pivotal role in modern surgical practice, providing targeted pain relief and improving patient outcomes. Unlike general anesthesia, which induces unconsciousness, regional anesthesia blocks pain sensations in specific regions of the body, allowing patients to remain conscious or sedated while the surgical procedure is performed. This method is widely used in various

Regional anesthesia is a critical component in modern pain management strategies, particularly for postoperative recovery. This technique involves the use of local anesthetics to block specific nerve pathways, providing targeted pain relief after surgical procedures. By offering effective and long-lasting analgesia, regional anesthesia minimizes the need for systemic pain medications, reducing side effects and enhancing

Regional anesthesia plays a pivotal role in ophthalmologic surgery by offering effective pain relief while allowing patients to remain awake and responsive during procedures. As ophthalmic surgeries continue to evolve, regional anesthetic techniques such as retrobulbar and peribulbar blocks have become essential in ensuring both patient comfort and surgical precision. These techniques provide targeted anesthesia

Effective pain management during labor is crucial for maternal satisfaction and favorable outcomes. Regional anesthesia, primarily epidural, spinal, or combined spinal-epidural (CSE) techniques, has become the gold standard for labor analgesia. These techniques provide targeted, reversible nerve blockade that allows mothers to remain awake, participate actively in childbirth, and experience significant pain relief. Types of

Regional anesthesia has become the standard of care for cesarean deliveries worldwide due to its superior maternal safety profile, effective analgesia, and the ability to maintain maternal consciousness during birth. Techniques such as spinal anesthesia, epidural anesthesia, and combined spinal-epidural (CSE) anesthesia are routinely employed, tailored to patient factors and clinical circumstances. Types of Regional

Refractory osteosarcoma refers to cases where the disease persists or recurs despite initial multimodal treatment involving surgery, chemotherapy, and sometimes radiotherapy. It represents a significant clinical challenge due to limited therapeutic options and a poor overall prognosis. Most refractory cases involve either local recurrence or distant metastases, primarily to the lungs. Pathophysiology and Mechanisms of

Refractory oropharyngeal candidiasis (OPC) is characterized by persistent or recurrent infection of the oral and pharyngeal mucosa caused primarily by Candida species, despite adequate courses of standard antifungal therapy, typically azoles. It is a significant complication, particularly among immunocompromised populations, including individuals with HIV/AIDS, cancer, or those receiving immunosuppressive therapies.
