Dieulafoy lesions: One patient, two different localizations.

Dieulafoy lesions (DLs) are dilated submucosal arterial structures visualized on endoscopy as bleeding foci on the superficial mucosa without erosion or ulceration. DLs account for 1-5.8% of acute non-variceal upper gastrointestinal bleeding cases. A 72-year-old male patient with known Alzheimer's disease and coronary artery disease, being followed up at a nursing home, presented to our emergency department with foul-smelling, loose, and tarry stool. Esophagogastroduodenoscopy revealed a 3 mm DL immediately adjacent to the Z line in the distal esophagus, demonstrating a fresh blood clot without the appearance of a surrounding ulcer. Two endoscopic hemo-clips were applied to this lesion. The patient was monitored at the intensive care unit for the following 2 days and later transferred to internal medicine inpatient unit. He developed hematochezia on the 8th day of hospitalization. Emergent rectosigmoidoscopy was performed showing two separate 3 and 4 mm sized DLs, located immediately proximal to the dentate line. These lesions were successfully treated using two endoscopic band ligations. DLs can occur synchronously, albeit very rarely, and a careful search for multiple lesions is necessary to avoid further bleeding.

Baseline characteristics associated with survival in patients with hepatocellular carcinoma.

Background and Aim: Hepatocellular carcinoma (HCC) is one of the most common and most lethal cancers worldwide. The objective of this study was to investigate the relationship between basal parameters and survival characteristics in patients with HCC. Materials and Methods: The records of 1447 HCC patients of a tertiary center during the period 2000-2017 were screened retrospectively. The demographic details; basal clinical, laboratory, and radiological characteristics; treatments; and survival time were recorded and prognostic scores were calculated. Results: A total of 788 patients with HCC (male/female: 623/165; mean age: 60.5±10.9 years) were included in the study. The median length of survival was 26.3 months (95% confidence interval [CI], 22.3-30.4 months). The 5-year survival rate was 28.1%. The number and diameter of the tumors; platelet count; platelet-to-lymphocyte ratio; level of aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transferase; portal and hepatic vein involvement; and an alpha-fetoprotein level of <9.6 ng/mL were found to be independently related to survival. Conclusion: The positive predictive value of the prognostic index derived from independent survival-related parameters for 5- and 10-year survival or overall survival was approximately 86%. Integration of this prognostic index to the criteria used in making treatment decisions for patients with HCC should be considered.

Outcomes of Patients with Acute Hepatotoxicity Caused by Mushroom-Induced Poisoning.

BACKGROUND: This study aimed to investigate the characteristics of severe hepatitis (SH), acute liver injury (ALI), and acute liver failure (ALF) in patients with mushroom-induced hepatotoxicity. METHODS: Data of patients between 2010 and 2019 were retrospectively reviewed. Twenty-four patients with mushroom-induced hepatotoxicity were included and divided into 3 groups: SH, ALI, and ALF. SH was defined as transaminase level ≥10 times ULN, international normalized ratio (INR) ≤1.5, and the absence of hepatic encephalopathy (HE). ALI was defined as INR > 1.5, presumed acute illness onset, and the absence of HE. ALF was diagnosed based on the presence of HE of any degree, with INR > 1.5, presumed acute illness onset, and the absence of cirrhosis. RESULTS: The mean age of the patients was 51.6 years; 13 (54.2%) were female. At admission, 18 patients (75%) had SH, 5 (21%) had ALI, and 1 (4.1%) had ALF. During follow-up, 6 of the 18 SH (33%) patients progressed to ALI and 2 of the 5 ALI (40%) patients progressed to ALF. No progression to ALI or ALF was observed in the 8 SH cases with a baseline MELD score of <15. One patient with grade 4 HE died (4.1%). None underwent liver transplantation. CONCLUSION: The survival was 100% in the ALI and SH groups. A MELD score of <15 at admission may be used as a predictor of no progression to ALI or ALF in patients with SH. However, since 40% of ALI cases may progress to ALF, these cases should be followed up in a tertiary care center that is equipped to perform liver transplantation and advanced therapies.

Hepatitis E virus IgG seroprevalence in liver transplant patients: A retrospective single-center experience.

Background and Aim: Hepatitis E virus (HEV) may cause chronic liver disease in solid organ transplant recipients. We determined HEV seroprevalence and associated factors in liver transplant recipients. Materials and Methods: Patients followed at the outpatient clinic of liver transplantation between January 2019 and January 2020 were screened retrospectively for HEV serology (HEV immunoglobulin M [IgM] and HEV immunoglobulin G [IgG]). Results: Of the 150 patients (male/female, 104/46; age, 55.4±13.2 years), anti-HEV IgG was positive in 31 (20.7%), and anti-HEV IgM was negative in all. The mean time after liver transplantation (72 [48%] deceased and 78 [52%] living donors) was 81±78.5 months. Drinking water consisted of carboy and tap water in 88 (58.7%) and 62 patients (41.3%), respectively. Of the patients, 120 (80%) and 30 (20%) lived in urban and rural areas, respectively. On comparison, the difference between positive and negative anti-HEV IgG groups in terms of age, place of birth, water supply, and donor type was statistically significant (p=0.007, p=0.000, p=0.034, and p=0.049, respectively). Conclusion: HEV seroprevalence was more frequent in liver transplant recipients compared with the normal population. Older age, water supply, and place of birth were risk factors for HEV seroprevalence.

Role of Allogeneic Stem Cell Transplant in the Treatment of Primary Myelofibrosis.

OBJECTIVES: The only known curative therapy for primary myelofibrosis is allogeneic hematopoietic stem cell transplant. MATERIALS AND METHODS: We retrospectively evaluated 11 transplant procedures involving 10 patients (5 men and 5 women) diagnosed with primary myelofibrosis between 2005 and 2014. RESULTS: The median age at the time of transplant was 60.5 years (range, 22-62 years). Stem cell sources were unrelated (n=1) and related (n=11) peripheral blood stem cells. Conditioning regimen was myeloablative for 8 and reduced intensity for 3 transplants. The median number of infused CD34+ cells was 6.8 × 106 cells/kg (range, 3.2-10.4 × 106 cells/kg). Neutrophil and platelet engraftment occurred at median of 22 days (range, 12-31 days) and 19.5 days (range, 13-56 days). Acute and chronic graft-versus-host disease was seen in 4 of 11 allografts. Relapse and nonrelapse mortality rates were 20%. Six patients (60%) were still alive without disease after median follow-up of 68.5 months (range, 17-120 months). Median progression-free survival and overall survival were 61 months (range, 2-120 months) and 65 months (range, 2-120 months). CONCLUSIONS: Our results suggest that allogeneic hematopoietic stem cell transplant may provide a curative treatment for primary myelofibrosis patients. A myeloablative regimen seems to be effective and safe, especially for younger primary myelofibrosis patients.

Phenolic compounds and vitamins in wild and cultivated apricot (Prunus armeniaca L.) fruits grown in irrigated and dry farming conditions.

BACKGROUND: Turkey is the main apricot producer in the world and apricots have been produced under both dry and irrigated conditions in the country. In this study, phenolic compounds and vitamins in fruits of one wild (Zerdali) and three main apricot cultivars ('Cataloglu', 'Hacihaliloglu' and 'Kabaasi') grown in both dry and irrigated conditions in Malatya provinces in Turkey were investigated. RESULTS: The findings indicated that higher content of phenolic compounds and vitamins was found in apricot fruits grown in irrigated conditions. Among the cultivars, 'Cataloglu' had the highest rutin contents both in irrigated and dry farming conditions as 2855 µg in irrigated and 6952 µg per 100 g dried weight base in dry conditions and the highest chlorogenic acid content in irrigated and dry farming conditions were measured in fruits of 'Hacihaliloglu' cultivar as 7542 µg and 15251 µg per 100 g dried weight base. Vitamin C contents in homogenates of fruit flesh and skin was found to be higher than ß-caroten, retinol, vitamin E and lycopen contents in apricot fruits both in irrigated and dry farming conditions. CONCLUSION: The results suggested that apricot fruits grown in both dry and irrigated conditions had high health benefits phytochemicals and phytochemical content varied among cultivars and irrigation conditions as well. However, more detailed biological and pharmacological studies are needed for the demonstration and clarification of health benefits of apricot fruits.
