RESUMO
Immunotherapy is gaining significance in the management of oncological disease. It has demonstrated high levels of efficacy, though it also has hitherto unknown side effects, such as colitis. We present the first case of immune checkpoint inhibitor colitis (nivolumab+ipilimumab) refractory to corticoids treated in our hospital.

BACKGROUND: bioelectrical impedance analysis is a technique for the determination of the hydropic component. The hydropic component, determined by blood volume, could be a reflection of the hemodynamic situation. This study aimed to evaluate the usefulness of peripheral bioelectrical impedance analysis (BIA) for the prediction of hemodynamic changes in large-volume paracentesis and prognosis. METHODS: this was a proof-of-concept prospective study of 14 patients with liver cirrhosis and refractory ascites. Peripheral bioimpedance was measured three times using a portable device, IVOL®, before and after large-volume paracentesis, at different frequencies (5, 10, 20, 50, 100 and 200 kHz). Consequently, resistance, reactance and phase angle were obtained, both pre- and post-paracentesis (the difference between them was defined as Δ). RESULTS: the mean age of patients was 62.2 ± 9.6 years, the Child-Pugh was 8.4 ± 1.3 and the MELD score was 15.2 ± 3.9. A direct correlation between the extraction of ascitic fluid and Δresistance (10 kHz [r = 0.722; n = 12; p = 0.008], 20 kHz [r = 0.658; n = 12; p = 0.020] and 50 kHz [r = 0.519; n = 14; p = 0.057]) was observed. The presence of edema was related to lower values of both pre-paracentesis resistance (10 Hz [23.9 ï± 8 vs 32.2 ï± 4; p = 0.043]) and phase angle (5 kHz [-1.9ï ï± 2.8 vs 5.9 ï± 7.3; p = 0.032]). Pre-paracentesis phase angle was directly correlated with the decline in blood pressure after paracentesis at lower frequencies (5 kHz [r = 0.694; n = 13; p = 0.008] and 10 kHz [r = 0.661; n = 13; p = 0.014]). Lower frequencies of Δphase-angle impacted on patient prognosis (5 kHz [-8.6 ± 5 vs -2.5 ± 2.7; p = 0.021]), patients with Δphase-angle 5 kHz > -4 had a higher rate of mortality (83.3% [5/6] vs 0% [0/6]; logRank 7.306, p = 0.007). Δresistance values were associated with overt HE at six months (10 kHz [4.9 ï± 2.5 vs -0.4 ï± 4.7; p = 0.046]). CONCLUSIONS: in conclusion, a significant correlation between peripheral impedance and hemodynamic changes was found. Impedance was also significantly related to prognosis and overt hepatic encephalopathy.

Epstein-Barr virus, a member of the Herpesviridae family, is responsible for the infectious mononucleosis clinical syndrome, which mainly includes the pharyngitis, fever, and lymphadenopathy triad after incubation for 30-50 days. The liver is involved in 80-90% of patients in a self-limiting transient manner, with jaundice being much more uncommon (5%). From a hematological standpoint it may manifest aplastic anemia, neutropenia, and thrombocytopenia. We report a case of infectious mononucleosis that included severe acute hepatitis and was associated with severe hemolytic anemia secondary to cold agglutinins. After exclusion of other etiologies, and given the clinical suspicion of the above association, which was later confirmed by lab tests, empiric therapy was initiated with antiviral agents (aciclovir + valganciclovir) and corticoids, which resulted in a progressive clinical improvement until complete remission. Therefore, we believe that this case report will reinforce the clinical evidence in support of the above combined therapy for serious infectious mononucleosis as a step prior to liver transplantation.

BACKGROUND: Colonic obstruction is a relatively common condition in emergency care, with a mortality rate of up to 20%. In 90% of cases it results from colonic or rectal adenocarcinoma, volvulus, or stenosis secondary to diverticular disease. When fecal impaction is the underlying cause, the condition is usually managed conservatively, but may on occasion become complicated and even require surgical intervention. Based on the proven efficacy of Coca-Cola® to dissolve gastric phytobezoars, we report a case of colonic obstruction secondary to sigmoid fecaloma. CASE REPORT: A 58 years old woman arrived at the Emergency Room (ER) with persistent constipation for the last six days. An abdominal CT scan showed a large fecal mass at the sigmoid colon with retrograde dilated colonic loops. Cleansing enemas and oral lactulose were administered, which failed to resolve the clinical presentation, so we then proceeded to inject Coca-Cola® within the fecaloma using a sclerosing needle, and then washed the fecaloma surface also with Coca-Cola®. After a few minutes we started to fragment the fecalith, the consistency of which had been notably decreased. DISCUSSION: The use of Coca-Cola® for gastric washes in the management of phytobezoars is well established. Since fecaliths are partly composed of these same substances than phytobezoars, the use of Coca-Cola® might well be warranted against them as in our patient, without surgery. Our case report is the second one published in the literature, in which Coca-Cola® helped solve colonic obstruction secondary to fecaloma.

BACKGROUND: Upper gastrointestinal bleeding (UGIB) is a common condition in gastroenterology, but "Downhill Varices" (DHV) or varices of the upper oesophagus are an uncommon cause of UGIB, with different aetiology from lower third oesophageal varices and different therapeutic implications. CASE REPORT: A 28-year-old male patient, with a history of chronic kidney failure secondary undergoing haemodialysis and superior vena cava syndrome (SCVS) due to multiple catheter replacements, was admitted to the Emergency Department with haematemesis secondary to a varicose vein rupture in the proximal third of oesophagus, treated initially with ethanolamine. Subsequent diagnostic studies showed the collateral circulation secondary to the SCVS. No further endoscopic or endovascular therapy could be performed and the patient will finally undergo a surgical bypass. DISCUSSION: DHVs are a very uncommon condition and endoscopic band ligation emerges as the appropriate therapeutic approach for the bleeding event. The definitive therapy continues to be that for the cause of the SVCS.
