    Background

    An important aspect of donor management is the optimization of serum sodium levels.

    Objective

    To perform a systematic review to determine the effects of donor sodium levels on heart, lung, kidney, and pancreas graft function, recipient mortality, and to identify the optimal donor serum sodium target.

    Methods

    We searched MEDLINE, Cochrane, Guideline databases, and trial registries from 1946 to May 2019 for studies investigating the effects of donor serum sodium levels on transplant outcomes in all nonhepatic organs. A two-step independent review process was used to identify relevant articles based on inclusion/exclusion criteria. We describe the results narratively, assess the risk of bias, and apply GRADE methodology to evaluate the certainty in the evidence.

    Results

    We included 18 cohort studies in our final analysis (n=28,007). 3 of 4 studies demonstrated an association between donor serum sodium and successful organ transplantation. 5 studies reported no association with graft function, while 6 studies did. 5 studies reported on recipient survival, 3 of which suggested donor sodium is unlikely to be associated with recipient survival. The included studies had serious risk of bias, and the certainty in evidence was deemed to be very low.

    Conclusion

    In low risk of bias studies, donor sodium dysregulation is unlikely to affect kidney graft function or mortality of heart and kidney recipients, but the certainty in the evidence is very low due to inconsistency and imprecision. Further research is required to refine the serum sodium target range, quantify the dose-response curve, and identify organs most vulnerable to sodium dysregulation.

    Background

    Free gingival graft is the most commonly practiced predictable technique for gingival augmentation.

    Objective

    To assess the effectiveness of human amniotic membrane, a biological dressing, on wound healing and post-operative pain after its application on the palatal donor site after free gingival graft surgery.

    Methods

    Of 27 eligible patients, 15 were randomized into a test group and received human amniotic membrane dressing sutured over their palatal donor site; 12 were randomized into a control group in whom the palatal donor site was only sutured. Standard clinical photographs were taken at 7, 14, and 21 days post-operatively and evaluated by 3 periodontists. The pain score at the donor site was assessed by a visual analog score; the number of analgesics taken was also recorded.

    Results

    The mean color match scores were higher in the test group than the control group at 14 (p<0.01) and 21 days after surgery (p=0.02). The difference in tissue texture (p=0.01) and inflammation (p=0.02) between the two groups was only significant on day 14 (p<0.05). The pattern of pain relief was better in the test group compared with the control group, especially in first days, although the differences were not significant in terms of the number of analgesics taken or the pain score.

    Conclusion

    Application of human amniotic membrane can accelerate wound healing and may decrease post-operative pain and discomfort by a limited amount

    Background

    Wilson’s disease (WD) is an autosomal-recessive hereditary liver disease affecting copper metabolism.

    Objective

    To test the diagnostic value of a questionnaire for the diagnosis of WD in pediatrics age group.

    Methods

    70 children with biopsy-proven diagnosis of WD and 70 without WD were included in the study. A modified questionnaire with 4 items was used for the diagnosis of WD. The results were then compared to the definite diagnosis made by pathology (the gold standard test).

    Results

    The median (IQR) modified score in those with WD was 4 (4–5), significantly (p<0.001) higher than that calculated for the comparison group, which was 0 (0–1). The most appropriate cut-off value for the score was 2.5, corresponding to a sensitivity and specificity of 100%, and 98.6%, respectively. Using this cut-off value to classify 20 children with and without WD who underwent liver transplantation resulted in an accuracy of 100%.

    Conclusion

    The modified scoring system is a sensitive and specific diagnostic tool for the diagnosis of WD in children. This is especially important in regions with limited access to specific laboratory tests for the diagnosis of WD.

    Background

    Immunosuppression is essential after liver transplantation (LT). It, however, increases the risk for cancer.

    Objective

    To evaluate the prevalence and outcome of upper gastrointestinal (GI) tract cancer in LT patients and assess the perioperative risk of surgery for the upper GI malignancies post-LT.

    Methods

    2855 patients underwent LT at our clinic from 1988 to 2018. 20 patients developed upper GI cancer. Data were retrospectively extracted from our database. Analysis included patients’ specific data, tumor histopathology and stage, the treatment given and survival.

    Results

    23 patients developed upper GI malignancies (2 gastric and 18 esophageal cancers; 3 excluded), translating to a incidence of 26.4 per 100,000 population per year. All patients were male. 80% showed alcohol-induced cirrhosis before LT. Most of the tumors were diagnosed at a stage ≥III. 70% underwent surgery and 78.6% developed postoperative complications. One-year-survival was 50%. Total survival rate was 28.6% with a median follow-up of 10 months (range: 0–184).

    Conclusion

    Upper GI malignancies are more common after LT compared to the general population. Men after LT, due to alcohol-induced liver cirrhosis, are at a higher risk. Upper GI surgery after LT can be safe, but the severe risk for complications and a poor survival require strict indications

    Background

    Probable effects of living donor liver transplantation on the wellbeing of the donor and psychological difficulties are necessary to be understood.

    Objective

    To assess the quality of life of living donors after liver donation.

    Methods

    140 living donors who underwent hepatectomy between 2012 and July 2015 were enrolled in this study. Donors were asked to complete the Short Form 36-question Health Survey (SF-36) through face to face or by telephone interview.

    Results

    The mean±SD age of donors at transplantation was 32.1±7.3 years; 83 (59.3%) of donors were female. 134 (95.7%) were married. The mean±SD BMI was 23.8±3.5 (kg/m2 ). “Mother-to-child” was the most frequent relationship (n=79, 56.4%). 22 (15.7%) complications were reported by participants. The mean±SD score of Physical Component Summary and Mental Component Summary were 48.8±14.6 and 50.1±6.9, respectively.

    Conclusion

    Most living donors sustain a near average quality of life post-donation. It seems that living donation does not negatively affect the quality of life.

    Heart transplantation is the treatment of choice for those with end-stage heart failure. However, despite improvements in immunosuppressive treatment, patients are at significant risk of allograft rejection, especially early after transplantation. Any changes in patient’s heart condition including reduced left ventricular ejection fraction, arrhythmia and any types of blocks need attention. Herein we report on a 29-year-old man who underwent heart transplantation 5 years before due to dilated cardiomyopathy. He was on immunosuppressive therapy and was good until one week before his admission, when he felt palpitation. Electrocardiography during palpitation showed a second-degree AV-block with heart rate of 60 beats/min. Echocardiography showed good left ventricular systolic function with no regional wall motion abnormality. The patient referred for coronary angiography and endomyocardial biopsy. The angiography was normal. The biopsy showed rejection compatible with ISHLT grade 2R. After treating the patient with 1.5 g methylprednisolone, the symptoms relieved and the block resolved. Bradycardia and second-degree AV-block late after heart transplantation could be a sign of cardiac allograft rejection and need more evaluation, especially endomyocardial biopsy.
