Background: Intravenous glutamine-enriched solution seems to be effective in posttransplant period in decreasing the severity and duration of mucositis. The aim of this randomized study was to determine the benefit of glutamine supplementation both on mucosal morbidity and in posttransplant associated complications.
Methods: Children undergoing allogeneic hematopoietic stem-cell transplantation (HSCT) for malignant hematological diseases were randomly assigned to standard total parenteral nutrition (S-TPN) or glutamine-enriched (GE)-TPN solution consisting of 0.4 g/kg/day of l-alanine-glutamine dipeptide. This treatment started on the day of HSCT and ended when the patients could orally cover more than 50% of their daily energy requirements. The severity and the rate of post-HSCT mucositis were based on World Health Organization criteria. All the analyses were conducted on intention-to-treat principle.
Results: One hundred twenty consecutive patients (83 men; median age, 8.1 years) were enrolled. The mean duration of treatment was 23.5 and 23 days in the two treatment arms. The mean calorie intake was 1538 kcal/d in the S-TPN group and 1512 kcal/d in GE-TPN group. All patients were well nourished before and after HSCT. Mucositis occurred in 91.4% and 91.7% of patients in S-TPN and GE-TPN arm, respectively (P=0.98). Odds ratio adjusted by type of HSCT was 0.98 (95% confidence interval, 0.26-2.63). Type and duration of analgesic treatment, clinical outcome (engraftment, graft versus host disease, early morbidity, and mortality, relapse rate up to 180 days post-HSCT) were not significantly different in the two treatment arms.
Conclusion: GE-TPN solution does not affect mucositis and outcome in well-nourished HSCT allogeneic patients.

Introduction: The purpose of this European multicenter study was to describe and assess the characteristics, diagnosis, management, and recurrence of oral malignant melanoma at different European oral and maxillofacial surgery centers.
Materials And Methods: This study was based on a systematic computer-assisted database that allowed the recording of data for all primary oral mucosal melanomas treated in the involved surgical units across Europe between January 1, 2003 and December 31, 2022. The following data were recorded for each patient: gender, age, site, TNM staging, metastases, symptoms, imaging features, histopathological features, treatment, complications, recurrence, follow up, and survival.

Bovine viral diarrhea (BVD) is caused by the BVD virus (BVDV) and has been reported worldwide in cattle. To estimate BVDV circulation among cattle where few BVD cases were reported in southern Japan, 1910 serum samples collected from 35 cattle farms without a BVD outbreak were investigated to detect antibodies against BVDV-1 and BVDV-2 using an indicator virus with a cytopathogenic effect and the luciferase gene, respectively. Neutralizing antibodies against BVDV-1 and BVDV-2 were detected more frequently in 18 vaccinated farms than in 17 nonvaccinated farms.

: Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are rare yet life-threatening dermatologic conditions characterized by severe skin and mucous membrane involvement. Accurate prognostic systems are crucial for clinical management to assess disease severity and predict outcomes. The primary objective of this study was to assess the epidemiological characteristics and clinical outcomes of patients with Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and SJS/TEN overlap over a 17-year period at a specialized burn center.

Studies on the gastric microbiota associated with gastric precancerous lesions remain limited. This study aimed to profile the gastric mucosal microbiota in patients with -negative precancerous lesions. Gastric mucosal samples were obtained from 67 -negative patients, including those with chronic gastritis (CG), intestinal metaplasia (IM), and dysplasia.

We have studied the presence and frequency of micronuclei in exfoliated oral mucosa cells of full-term newborns and their association with maternal prenatal factors. We report an analytical, observational, cross-sectional, prospective study that includes 97 preterm infants (<37 weeks), 37 newborns from mothers with comorbidities, and 60 newborns from mothers without comorbidities, in a tertiary public hospital. Oral mucosa cells were collected within 24 h after birth.
