Adverse effects of irrevocable electroporation associated with malignant liver cancers beneath CT fluoroscopic guidance: a single-center encounter.
Oxaliplatin is a new generation of platinum derivatives used frequently to treat solid organ malignancies, including colorectal and ovarian cancer. Recently, an oxaliplatin-based chemotherapeutic regimen was adopted for advanced pancreatic cancer. Although oxaliplatin has extensive therapeutic potential, its use can be limited by significant adverse effects, particularly ototoxicity. This paper reports a rare case of irreversible unilateral hearing loss in a 48-year-old female that developed after the intravenous infusion of oxaliplatin during pancreatic cancer treatment. To the best of the authors' knowledge, this is the second reported case of oxaliplatin-related ototoxicity in pancreatic cancer.Although rare patients with chronic hepatitis B can achieve HBsAg loss on oral nucleos(t)ide analog (NA), the optimal timing of stopping oral NAs safely has been considered when HBsAg and HBV DNA are negative in the serum because HBsAg loss induced by nucleos(t)ide analogs (NAs) appears to be durable if immunosuppressive therapy or chemotherapy are not done. On the other hand, the author experienced a case of HBsAg seroreversion and acute decompensation after the discontinuation of NA in a patient with HBsAg loss. This rare case highlights the need for the close monitoring of patients who achieved HBsAg loss and stopped NA.The World Health Organization classified rectal neuroendocrine tumors (NETs) as malignant in 2010 owing to their distant metastasis potential. On the other hand, in cases of small rectal NETs ( less then 10 mm), which have a low risk of metastasis, endoscopic removal is the first-line therapeutic option, and regular surveillance is not recommended. The authors report a case of a small, well-differentiated rectal NET, which recurred as multiple hepatic metastases 5 years after apparent complete removal using endoscopic methods.Colonoscopy is a safe and extremely popular diagnostic and therapeutic procedure. The most common complications are bleeding and perforation. Hemoperitoneum is a rare complication after a colonoscopy and is usually associated with splenic injury or solid organ pathology. This is potentially serious and can be life threatening. Ferroptosis activator With the increasing number of colonoscopies performed, there has also been an increasing trend in reports of rare complications, such as pneumothorax, pneumomediastinum, appendicitis, small bowel perforation, septicemia, mesenteric tear, retroperitoneal abscess, and hemoperitoneum. This paper reports a unique case of hemoperitoneum after a recent colonoscopy without a splenic rupture or intra-abdominal abnormality, or external trauma. Most hemoperitoneum occurs within 48 hours after the inciting colonoscopy. In the present case, however, hemoperitoneum appeared 10 days after the colonoscopy. This case emphasizes that physicians should consider hemoperitoneum in a differential diagnosis of abdominal pain in patients after colonoscopy.Antiplatelet and anticoagulation agents are increasingly prescribed for secondary prophylaxis in patients with cardiovascular and cerebrovascular diseases. These drugs are associated with an increased risk of gastrointestinal bleeding, including peptic ulcer bleeding. It is difficult to decide when to restart the agents after peptic ulcer bleeding in these patients because the risk of rebleeding and thromboembolism should be balanced. The Korean College of Helicobacter and Upper Gastrointestinal Research revised the guidelines for drug-induced peptic ulcers as evidence-based guidelines using a de novo process. This paper introduces new recommendations on the resumption of antiplatelet and anticoagulation agents after peptic ulcer bleeding based on the revised guidelines for drug-induced peptic ulcers.The Korean guidelines for the Clinical Guidelines for Drug-related Peptic Ulcer were revised under the Korean College of Helicobacter and Upper Gastrointestinal Research in 2020. In these revised guidelines, treatment for Helicobacter pylori infections is recommended in patients with a history of peptic ulcers and are receiving long-term low-dose aspirin therapy to prevent peptic ulcers and complications. The maintenance of anti-ulcer drugs, such as proton pump inhibitors, is also recommended after H. pylori eradication if patients require other antiplatelet agents or anticoagulants. Regardless of H. pylori eradication, when patients with a history of peptic ulcer take long-term low dose aspirin, the concomitant use of a proton pump inhibitor according to the severity of the peptic ulcer is recommended.Nonsteroidal anti-inflammatory drugs (NSAID) are some of the most commonly prescribed medications in clinical practice. The long-term use of NSAIDs is one of the main causes of peptic ulcers and the increased risk of upper gastrointestinal tract complications, such as perforation and bleeding. Thus, the prevention of NSAID-induced peptic ulcers is an important clinical issue. Previous studies have evaluated various strategies for preventing ulcers in patients requiring prolonged NSAID use. The Korean clinical practice guidelines have been published recently based on the evidence of the currently available data. This review describes the strategies for the prevention of peptic ulcers due to NSAID. An assessment of the risk factors for peptic ulcers from NSAID is recommended to identify patients who should be considered for primary prophylaxis. The risk of NSAID-induced peptic ulcers can be reduced by the concomitant use of proton pump inhibitors (PPI), misoprostol, and histamine-2 receptor antagonists. Selective cyclooxygenase-2 inhibitors can be used with caution due to concerns regarding cardiovascular toxicity. Attempts should be made to use the lowest dose and shortest duration of the NSAID.Non-steroidal anti-inflammatory drugs (NSAIDs) and aspirin are the most frequently prescribed drugs worldwide, and their long-term use often leads to peptic ulcers (PUs) along with serious complications, such as bleeding and perforation. Helicobacter pylori (H. pylori) infection is a significant risk factor for developing NSAID-related PU and ulcer bleeding during long-term aspirin use. In a revised version of the Clinical Guidelines for Drug-induced Peptic Ulcer, two statements regarding H. pylori eradication are recommended. 1) Patients scheduled for long-term NSAID therapy should be tested and treated for H. pylori infection to prevent PU and its complications. 2) Patients with a history of PU receiving long-term low-dose aspirin (LDA) therapy should undergo treatment for H. pylori infection to prevent PU and its complications. On the other hand, unlike NSAID-naïve patients, the preventive effects of H. pylori eradication in chronic NSAID users are unclear. In addition, anti-ulcer drugs, such as proton pump inhibitors, may be necessary for maintenance therapy after H.
