Pancreatic Cancer

#pancreatic cancer, #chemotherapy, #abdominal CT, #jaundice, #chronic pancreatitis

Pancreatic cancer is cancer that develops in the pancreas, an organ located deep within the body. Because it produces few early symptoms, it is often found at a later stage. Please do not attempt to self-diagnose using an online encyclopedia; if you notice any concerning symptoms, be sure to see a gastroenterology or hepatobiliary-pancreatic surgery specialist.

Panic disorder is a mental illness characterized by sudden, recurrent, intense attacks of anxiety (panic attacks), in which a person feels a pounding heart, difficulty breathing, and a fear of dying even though there is no real danger. Repeated attacks are often accompanied by constant worry about having another attack (anticipatory anxiety), which can greatly reduce quality of life. Symptoms can be managed with medication and cognitive behavioral therapy, and if you suspect panic disorder, please consult a psychiatrist.

If you have suspected symptoms, please consult a pulmonology and allergy specialist immediately.

Post-Cardiac Arrest Integrated Care

#cardiac arrest, #cardiopulmonary resuscitation, #defibrillation, #chain of survival, #targeted temperature management, #heart, #emergency

Cardiac arrest is a condition in which the heart stops, cutting off the blood supply to the brain and the rest of the body. Without emergency care within 3 to 5 minutes, serious brain damage can occur, so immediate treatment such as CPR and defibrillation is important, and integrated care by a specialized medical team is needed afterward. If cardiac arrest is suspected, call 119 immediately and receive treatment from a medical specialist.

Prostate Cancer

#prostate cancer, #PSA, #prostate-specific antigen, #robotic surgery, #radiation therapy, #prostate biopsy, #family history, #androgen deprivation therapy, #early screening

Prostate cancer often has no symptoms in its early stages, so it is frequently discovered only after it has progressed significantly. Early detection is possible through the PSA (prostate-specific antigen) blood test, and when found early, surgery or radiation therapy can offer a favorable outlook. Regular screening is important for men age 45 and older, especially those with a family history.
