Background Post reperfusion syndrome (PRS) is a relatively common and life-threatening complication during orthotopic liver transplantation (OLT). It is associated with poor patient and transplanted liver outcomes. Objective This study aimed to compare the risk factors of PRS during OLT. Design Clinical-epidemiological observational retrospective study. Setting We gathered the records of patients who underwent OLT in 3 years, from May 22, 2016, to May 22, 2019, in Namazi and Bu-Ali Sina organ transplantation hospitals. Patients In this study, we assessed 1182 patients who underwent OLT. Patients were divided into two groups based on the presence or absence of PRS. Main outcome measures Diagnosing the predictors of PRS was the primary outcome of this study. Results Results showed that age > 60 years, Child-Pugh scores C, higher Model End Stage liver disease score, and preoperative sodium < 130 mmol/l (parameters of the liver recipient), increase in cold ischemic time (the donors’ parameters), and the classical technique (the surgical parameters) were the strong predictors of PRS. Conclusions The results indicated that underlying liver disease was not the predictor of PRS in the presence of other risk factors; therefore, clinicians have to consider these risk factors in patients undergoing OLT.
Differentiated thyroid carcinoma is rare in patients younger than 21 years, especially in children, but it is associated with a greater risk of metastases and recurrence. The aim of our study was to compare the characteristics, clinical course, and outcome of the disease between young children (≤16 years) and adolescents (17-21 years). We reviewed the medical records of 62 young children and adolescents (47 females, 15 males, ≤21 years) with DTC who were diagnosed between 1990 and 2010 and admitted for radioiodine therapy, and compared the histopathologic features, amount and session(s) of radioiodine administration, and outcome in both groups. Young children presented with larger tumor size, more aggressive pathological features, higher incidence of locoregional and distant metastasis, and needed more admissions, and higher amounts of radioiodine for treatment. While there were more disease-free patients at the end of follow-up in the adolescents, the number of patients with stable or progressive disease was higher in younger group. Based on the results of our study, we support the more aggressive approach to DTC treatment in young children, including total thyroidectomy along with more extensive cervical lymph node dissection, L-T4 therapy in suppressive doses, and multiple sessions of postsurgical radioiodine therapy as necessitated.
Background. Rhinocerebral mucormycosis is a serious invasive fungal infection that is one of the most aggressive and lethal of invasive mycoses. The coronavirus disease (COVID-19) has been linked to immune dysregulation, and patients with COVID-19 have been reported to be at risk for developing invasive fungal infections. This study is conducted to evaluate the concurrence of mucormycosis among COVID-19 patients. Methods. In this retrospective, cross-sectional study, hospital records of patients with mucormycosis, as well as COVID-19 admitted to Khalili Hospital, as the major referral center for functional endoscopic sinus surgery (FESS) in southern Iran, were collected. Demographic and clinical information was extracted and subsequently analyzed. Results. Among 59 mucormycosis patients undergoing FESS, 41 (69.5%) were during the COVID-19 pandemic, while 18 (30.5%) were during one year before the COVID-19 pandemic. The average age was 49.33 ± 20.52, and 64.4% had diabetes mellitus, while 62.7% had COVID-19. The most common presentation was periorbital edema (56.9%), followed by necrotic tissue (48.3%). Although the total number of cases increased during the COVID-19 period compared to the case before the pandemic, the overall pattern and features of the patients had no significant difference, except regarding a significant increase in the presentation of necrotic tissue and also the use of corticosteroids. Most cases developed mucormycosis two weeks after COVID-19. The overall mortality was 36.8%, which is not statistically associated with COVID-19. Conclusion. Even in the absence of comorbidities, physicians should be aware of the risk of secondary fungal infections in patients with COVID-19 who were treated with corticosteroids.
Background: Many regions of the world, especially middle- and low-income countries, lack facilities for home parenteral nutrition and thus cannot follow existing guidelines for intestinal transplantation. Herein, we report our experiences with treatment protocols, intraoperative management, and early postoperative outcomes among patients undergoing either isolated intestinal transplantation or multivisceral transplantation in our center. Methods: During a 1-year period from March 2019 to March 2020, a total of 9 intestinal transplantations including 6 isolated intestinal transplantations and 3 multivisceral transplantations were performed in our center. We reported on donor selection strategies, surgical treatment, anesthesiology care and protocols for total parenteral nutrition, immunosuppression regimen, and pathology evaluation. Results: Mean (standard deviation) age of patients was 37.5 ± 12.5 years. The majority of patients were females (7/9). The median (interquartile range) waiting time for patients from diagnosis to transplantation was 79 (34, 164) days. Our 7-day survey of the amount of fluid therapy after transplantation revealed that the greatest need for fluid therapy was seen on the second postoperative day. After transplantation, 2 patients showed a total of 3 episodes of severe rejection, 1 of which was antibody-mediated. The 1-year survival was 66.6% and the 2-year survival was 44.5% in our study population. The median (interquartile range) time to death was 157 (26.5, 382) days. The most common cause of death was sepsis in our series (3/5). Conclusion: Acceptable outcomes can be obtained with intestinal transplantation in countries without home parenteral nutrition by application of specific treatment protocols.
