A plethora of paraneoplastic syndromes have been reported as remote effects of colorectal carcinoma (CRC). However, there is a dearth of data pertaining to the association of this cancer with demyelinating neuropathies. Herein, we describe the case of a young woman diagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP). Treatment with intravenous immunoglobulins and prednisone did not improve her condition, and her neurological symptoms worsened. Subsequently, she was readmitted with exertional dyspnea, lightheadedness, malaise, and black stools. Colonoscopy revealed a necrotic mass in the ascending colon, which directly invaded the second part of the duodenum. Pathologic results confirmed the diagnosis of locally advanced CRC. Upon surgical resection of the cancer, her CIDP showed dramatic resolution without any additional therapy. Patients with CRC may develop CIDP as a type of paraneoplastic syndrome. Clinicians should remain cognizant of this potential association, as it is of paramount importance for the necessary holistic clinical management.

Background and aims Anti-neoplastic immunotherapy has revolutionized cancer management; however, its safety profile with respect to liver-related injury remains largely unexplored. Herein, we analyzed a United States national database to determine the incidence, mortality, and predictors of hepatotoxicity in the setting of anti-neoplastic immunotherapy. Methods This was a nationwide retrospective study of hospital encounters from 2011 to 2014 using the National Inpatient Sample (NIS) database. We utilized the International Classification of Diseases, Ninth Revision (ICD-9) coding system to identify all adult patients who underwent anti-neoplastic immunotherapy during hospitalization. The primary outcome was the incidence of hepatotoxicity during the same hospitalization. Secondary outcomes included in-hospital mortality as well as socioeconomic and ethno-racial predictors of hepatotoxicity. Analyses were performed using IBM SPSS Statistics 23.0. Results The sample included 3002 patients who underwent inpatient anti-neoplastic immunotherapy. The incidence of hepatotoxicity was 10.1%, which was significantly higher as compared to a matched inpatient population (adjusted odds ratio (aOR) 4.93, 95% confidence interval (CI): 3.80–6.40, P = 0.001). No significant mortality difference was seen in those that developed hepatotoxicity compared to those who did not (aOR 0.47, 95% CI: 0.03–8.03, P = 0.612). Age under 60 (aOR 1.56, 95% CI: 1.23–1.78, P = 0.050) and white race (aOR 1.85, 95% CI: 1.35–2.04, P<0.010) were independent risk factors for developing immunotherapy-associated hepatotoxicity. Conclusions In this large, nationwide database analysis, we found that anti-neoplastic immunotherapy was associated with a nearly five-fold risk of in-hospital hepatotoxicity as compared to a matched inpatient population, though without an associated mortality difference. Additionally, younger age and white race were identified as predictors of immunotherapy-associated hepatotoxicity. Heightened vigilance and prospective investigation of the risk factors and liver-related adverse effects of anti-neoplastic immunotherapy are warranted.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, primarily arising from the stomach. With the widespread utilization of and technical advancements in endoscopy, gastric GISTs are being increasingly detected at an early stage, enabling complete endoscopic resection. Endoscopic full-thickness resection (EFTR) is an advanced technique that has been recognized as a treatment tool for neoplasms in the digestive tract in selected patients. Although a number of methods are available, closing large iatrogenic defects after EFTR can be a concern in clinical practice. If this potential problem is appropriately solved, patients with gastric GISTs would be suitable candidates for resection utilizing this technique. To our knowledge, this is the first study to propose omental patching and purse-string endosuture closure following EFTR as a feasible endoscopic option in patients with gastric GISTs.

Dengue virus infection affects the heart structurally and functionally. Clinical manifestations of cardiac complications secondary to dengue virus infection vary from self-limiting arrhythmias to severe myocardial infarction, leading to hypotension, pulmonary edema, and cardiogenic shock. However, we report a case of dengue hemorrhagic fever (DHF) complicated by a complete heart block. A female with DHF due to dengue virus serotype 2, presented to the emergency department with fever, headache, rash, and fatigue followed by an episode of syncope. She was found to have a third-degree atrioventricular block, with pulseless polymorphic ventricular tachycardia. Patient was resuscitated and a temporary trans-venous pacemaker was placed. She reverted back to normal sinus rhythm after 4 days of syncope and was subsequently discharged from the hospital after complete resolution of symptoms, without the need for a permanent pacemaker. Physicians are warranted to have high index of suspicion for dengue virus infection as an etiology in patients with acute cardiovascular compromise, especially in tropical areas.
