Split Liver Transplant From Deceased Marginal Donor: A Case Report.

The relative paucity of deceased donor organs and the progressive increase in patients with cirrhosis have led transplant centers to consider organs from marginal donors (elderly donors, prolonged stay in the intensive care unit (ICU), liver steatosis-steatotic grafts, severe hypernatremia, and use of inotropes). Recently, the use of those marginal grafts has increased, but splitting liver is still debatable. Herein, we present a 28-year-old deceased donor who had a history of traumatic brain injury. The patient stayed in ICU for 3 days with high sodium level (188 mEq/L) and was hemodynamically supported with single inotrope. At the time of procurement, core biopsies were taken from the right lobe and left lateral segment of the liver, with results demonstrating 5% necrosis. A decision was made for split liver transplant as left lateral sector and extended right lobe. Liver graft was divided into a left lateral segment to be transplanted to a 4-year-old child with secondary biliary cirrhosis due to previous liver transplant and a right extended liver lobe for an adult patient with hepatocellular carcinoma waiting 10 months on the waiting list. Both liver transplants were performed uneventfully. Patients were discharged on the 11th and 56th days after transplant. The liver function tests remained normal during the follow up period of 2 years. A marginal graft with more than one risk factor should not be discarded liberally. Splitting such grafts could be considered in a highly selective recipients.

Anatomical variations of the hepatic artery: a closer view of rare unclassified variants.

BACKGROUND: Defining the hepatic artery anatomy is of great importance for both surgeons and radiologists. Michel classification was designed to classify hepatic artery variations. Nevertheless, there are variations that do not fit into this classification. In this study, we aim to define the incidence of all variations in a healthy liver donor by reviewing their computed tomography (CT) scan with special emphasis on variations that do not fit in any of the Michel classes. MATERIALS AND METHODS: A retrospective analysis of CT scan of donors and potential liver donors who were evaluated by triphasic CT scan. The CT scans were reviewed independently by a radiologist and two transplant surgeons. Cases that did not fit in any of the Michel classes were classified as class 0. RESULTS: Out of 241 donors, 210 were classified within the Michel classification, of which 60.9% were class I and 9.1% class II. Thirty-one (12.9%) donors classified as class 0. Of which, nine, three, two and three had replaced right hepatic artery from pancreaticoduodenal artery, gastroduodenal artery, aorta and coeliac artery, respectively. Two and six donors had accessory right hepatic artery from pancreaticoduodenal artery and gastroduodenal artery, respectively. Segment 4 artery originated from left and right hepatic artery in 56.8% and 31.9%, respectively. CONCLUSIONS: A great caution should be taken when evaluating the hepatic artery anatomy, clinicians should anticipate and be familiar with the rare unclassified variations of the hepatic artery.

Urgent Liver Transplantation from Deceased Donor With a Calcified Hydatid Cyst: A Case Report.

Liver transplantation is the final treatment option for end-stage liver disease and acute liver failure, although availability of donor organs is a major limitation. The large gap between the growing list of patients awaiting liver transplantation and the scarcity of donor organs has fueled efforts to maximize the existing donor pool and identify new avenues. We treated a 13-year-old boy who had acute liver failure, due to Wilson's disease, with transplantation of a liver from a deceased liver donor with a calcified hydatid cyst. After 3 years of follow-up, liver function tests remained normal, hydatid cyst serology was negative, and no hydatid cyst or other problems were observed.

Three Consequent Pediatric Liver Transplant Deaths in the COVID-19 Era.

The effect of COVID-19 on the transplant recipients is not well-established. Many reports underestimate the effect of COVID-19 on the immunosuppressed population. Herein, we report on 3 pediatric liver transplant recipients who were transplanted at our center between February 11 and March 10, 2020-during the COVID-19 pandemic era. The 3 patients aged between 5 and 10 months, had a rapid and aggressive respiratory deterioration that necessitated mechanical ventilation and extracorporeal life support; and eventually died. The clinical and pathological pictures likely represent COVID-19 pneumonia. Chest x-rays showed progressive infiltrates. Lung autopsies showed diffuse alveolar damage in two cases. We concluded that COVID-19 is very likely to have catastrophic effects on transplant recipients.

Beliefs of Living Donors About Recipients' End-Stage Liver Failure and Surgery for Organ Donation.

BACKGROUND: The concept of beliefs could provide a basis for how donors may perceive recipients' end-stage liver failure (ESLF) and surgery for organ donation. However, there is no such quantitative study. Therefore, the objective of this study was to explore beliefs of living donors about recipients' ESLF and surgery for organ donation. METHODS: The sample comprised 16 living donors who donated a part of their liver to a patient who had ESLF. The data were analyzed by following established procedures for inductive qualitative analysis. RESULTS: Analysis showed that donors' beliefs can be viewed in a number of groups. Beliefs about recipients' ESLF included diverse explanations for ESLF (blaming oneself and physicians) and physical symptoms (developmental slowing down). Beliefs about being a donor included reasons for being a donor (performing a good deed, being healed), barriers to being a donor (other people being ignorant and selfish), ways to manage these barriers (following one's gut feeling), and factors facilitating being a donor (the feeling that one does not have many people to leave behind). Beliefs about surgery for organ donation included physical effects (pain, feeling stiff). Beliefs about organ donation included views that general organ donation should be encouraged and that people's awareness should be raised. CONCLUSIONS: Existing psychological perspectives could help to interpret some beliefs. Nevertheless, other beliefs, not previously reported, could be considered as targets for individual consultations/psycho-educational programs for fostering emotional well-being.

Liver Transplantation: Recipients' Evaluation of Life From the Perspective of Living Donors.

AIM: Liver transplantation affects not only recipients and living donors' lives, but also the nature and quality of their relationship. Moreover, the ways in which recipients of liver transplant experience life and views of living donors on how recipients experience life may differ. These differences may account for relational changes. It is also important to understand how recipients and their living donors' views differ if the aim is to devise psychoeducational programs for recipients and living donors. Therefore, the present study examined the recipients' experience of life after a diagnosis of end-stage liver failure (ESLF) and transplantation surgery from donors' perspective. METHODS: The sample consisted of 16 living donors who donated a part of their liver to a patient with ESLF. Thematic analysis was undertaken in parallel with interviews during which an interview guide was followed. FINDINGS: Donors felt that recipients evaluated life after the diagnosis of ESLF and transplantation surgery in terms of limitations, mixed relationships, emotional changes, and improvement in life. CONCLUSION: Experience of social limitations, negative emotions, and the feeling that one is supported by others could be interpreted in terms of existing psychological theory. Some ways of adjusting that have not been reported before within the context of ESLF extended the literature. These included others being frightened of being infected by ESLF and being insensitive, experience of positive emotions, and ways of improving. Overall, compared with findings of previous qualitative work among recipients, our findings suggest that donors' evaluation of recipients' lives converge with that of recipients.

Living donor liver transplantation: a life-saving option in emergency situations for diffuse hepatic neuroendocrine tumor metastasis.

Liver metastasis is the main cause of death in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs), but only 10%-20% of metastasis in these cases is resectable at the time of diagnosis. In some cases, medical and interventional radiological treatments may not be effective. Liver transplantation, although controversial, may be an option. Worldwide organ-sharing systems do not provide exception points, but give recommendations for liver transplantation in cases of hepatic metastasis from GEP-NETs due to the issue of fair access to donor organs. Living donor liver transplantation is an option in select cases. Presented here are 2 cases in which living donor liver transplantation was performed in emergency situations as a life-saving procedure, with acceptable survival and without donor complications.

Acquired factor XI deficiency: a rare complication after liver transplantation.

BACKGROUND: A majority of coagulation factors are synthesized in the liver. Factor XI (FXI) deficiency (Rosenthal syndrome) is one of the rare inherited coagulation disorders with an extremely low risk of transmission by liver transplantation (LT). CASE REPORT: We report here the case of a 50-year-old man who unknowingly acquired FXI deficiency by LT. During 1 year of post-transplant follow-up, his activated partial thromboplastin time (aPTT) remained prolonged, but he did not develop bleeding complications. The patient required retransplantation due to chronic rejection and is currently doing well 4 years after his first liver transplantation. CONCLUSIONS: The presence of a prolonged aPTT in a deceased donor should raise suspicion for the presence of rare coagulation factor deficiencies. During urgent, lifesaving procedures such as LT, it may be impossible to avoid transmission. Awareness of this possibility will allow early detection and management.

What has changed in pediatric kidney transplantation in Turkey? Experience of an evolving center.

INTRODUCTION: Reluctance to perform kidney transplantations on children is an ongoing problem in Turkey. Moreover, urological pathologies still constitute the largest portion of the underlying etiologies in chronic renal failure patients. Herein, we retrospective analyzed the data acquired from our pediatric renal transplantation patients and reviewed the registry of dialysis and transplantation data prepared by the Turkish Society of Nephrology. MATERIAL AND METHODS: Forty-six living donor kidney transplantations were performed in children between 2008 and 2012. Seventeen of 46 (37%) transplantations were preemptive. The mean age at operation time was 10.8 ± 5 years. The mean patient weight was 31.3 ± 15.8 kg (range, 9.4 to 66.4 kg). A detailed urologic evaluation was performed for every child with an underlying lower urinary tract disease. One enterocystoplasty and 2 ureterocystoplasties were performed for augmentation of the bladder, simultaneously. RESULTS: One-year death-censored graft survival and patient survival rates were 100% and 97.8%, respectively. The mean serum creatinine level was 0.86 ± 0.32 mg/dL (range, 0.3 to 1.8 mg/dL). None of the patients had vascular complications or acute tubular necrosis. One patient suffered graft-versus-host disease during the second month after renal transplantation and died with a functioning graft. In one patient with massive proteinuria detected after transplantation, recurrence of primary disease (focal segmental glomerulosclerosis) was considered and the patient was treated successfully with plasmapheresis. One child had an acute cellular rejection and was administered pulse steroid treatment. CONCLUSION: Although challenging, all patients in all pediatric age groups can successfully be operated and managed. With careful surgical technique, close postoperative follow-up, and efforts by the experienced and respectful surgical teams in this country, we could change the negative trends toward perform kidney transplantation in the Turkish pediatric population.

Cadaveric liver transplantation in biliary atresia splenic malformation syndrome with the absence of retrohepatic inferior vena cava, preduodenal portal vein, and intestinal malrotation: a case report.

A 9-month-old female infant with biliary atresia underwent cadaveric liver transplantation due to progressive cholestatic hepatitis following a Kasai operation. She had biliary atresia splenic malformation syndrome (BASM) composed of an absent retrohepatic inferior vena cava with an azygous connection, preduodenal portal vein, polysplenia, and intestinal malrotation. A portal vein thrombosis developed on the 4th postoperative day requiring immediate treatment by thrombectomy. The patient is well with normal liver function at 3 months follow-up. Although BASM may render the transplantation more difficult, the presence of BASM is no longer a contraindication to liver transplantation.

Electrophysiological evaluation of cremasteric reflex in experimental testicular torsion.

AIM: The aim of the study was the electrophysiological evaluation of the cremasteric reflex after experimental testicular torsion. MATERIAL AND METHODS: Ten male Wistar rats were enrolled into the study. Genitofemoral nerve (GFN) motor conduction and cremasteric reflex (CR) responses were evaluated electrophysiologically after being subjected to anesthesia with intramuscular ketamin hydrochloride. Testicular torsion was performed by rotating the right testicle 720 degrees in a clockwise direction from a midscrotal incision. Electrophysiological evaluations were repeated in the early (30 minutes) and late (90 minutes) periods of testicular torsion. Subsequently, detorsion of the testicles was performed and electrophysiological recordings were completed after 60 minutes of detorsion. The CR was also evaluated clinically before each electrophysiological evaluation. The latency and duration of GFN motor conduction and CR responses was compared for base, early torsion, late torsion and detorsion recordings. Friedman's test for repeated measurements was used for statistical analysis. RESULTS: The CR, which was detected clinically before torsion and after detorsion, was not detected during torsion. When base, early torsion, late torsion and detorsion recordings were compared, there was no statistical difference with respect to both latency and duration of GFN motor conduction and CR responses (p > 0.05). CONCLUSION: Although CR was not detected clinically during testicular torsion, the electrophysiological parameters of the reflex did not differ in the early and late periods of torsion in rats. The GFN motor conduction parameters also showed no differences. In conclusion, the absence of the CR after testicular torsion could not be confirmed by electrophysiological studies.

Evaluation of systemic oxidative status and mononuclear leukocytes DNA damage in children with caustic esophageal stricture.

Esophageal stricture (ES) due to accidentally caustic digestions is a common problem in children. Mucosal damage and repeated dilatations lead to chronic inflammation and finally ES. We investigated the oxidative status and DNA damage of children with ES. Five children with ES were compared with the same age- and sex-matched healthy subjects. Oxidative status of plasma was evaluated by measuring myeloperoxidase (MPO) activity, and total peroxide (TP) level. Anti-oxidative status of the plasma was evaluated by measuring catalase (CAT) activity, and total antioxidant response (TAR). We used the Single Cell Gel Electrophoresis (also called Comet Assay) to measure DNA strand break in peripheral blood mononuclear leukocytes. Mean MPO activity and TP levels in the ES group were significantly higher than the control group (0.83 +/- 0.35, 0.09 +/- 0.03 and 0.98 +/- 0.38, 0.34 +/- 0.20, P = 0.009 and P = 0.047 respectively). There was no significant difference in CAT activity and TAR levels between the two groups (P = 0.347). DNA damage in patients with ES was increased compared to control subjects (108.8 +/- 51.2 and 57.6 +/- 31.2 arbitrary units, respectively), but this difference was not significant statistically (P= 0.09). This study shows that systemic oxidative stress and alteration at the nuclear level occur in patients with ES, as a result of multiple dilatations and tissue injury. On the other hand, these results support that patients with ES may benefit from antioxidant treatment.

Total antioxidant capacity in children with acute appendicitis.

AIM: This study aimed to investigate antioxidant capacity by using a novel automated method in children with acute appendicitis. METHODS: Blood samples were obtained from consecutive patients with acute appendicitis (appendicitis group, n = 12) and acute abdominal pain due to non surgical disease (non-appendicitis group, n = 11), and from patients with inguinal hernia (healthy group, n = 12) as the control group. At admission, total antioxidant capacity (TAC) levels of plasma were evaluated in all patients by a method recently developed by Erel. Four other major individual plasma antioxidant components, the levels of total protein, albumin, uric acid and bilirubin, were also evaluated. Total antioxidant capacity in patients with acute appendicitis was statistically compared with the two other groups. RESULTS: While the TAC level in the appendicitis group was significantly greater than in the non-appendicitis group, no significant difference was found in healthy groups (p < 0.05, p > 0.05, 1.94 +/- 0.38, 1.40 +/- 0.36, and 1.99 +/- 0.35 respectively). Individual components of total antioxidant capacity, i.e. total protein, albumin, uric acid and bilirubin concentrations, were also higher in the patients with acute appendicitis than those of the other two control groups. CONCLUSIONS: Our data show that children with acute appendicitis do not have deficient blood plasma antioxidant capacity. These results provide evidence that acute appendicitis results in more induction of antioxidative response than non-surgical diseases.

The effect of amnio-allantoic fluid pH on the intestines: an experimental study in the chick embryo gastroschisis model.

BACKGROUND/PURPOSE: Prolonged exposure to amniotic fluid causes the intestinal changes such as serosal edema, thickening, fibrous coating, and adhesions in gastroschisis. The effect of amnio-allantoic fluid (AAF) pH on intestines was evaluated using a chick embryo gastroschisis model. METHODS: Seventy fertile eggs were divided into 5 groups: preliminary study (PS, n = 20), AAF control (AAC, n = 10), just gastroschisis (JG, n = 10), gastroschisis pretreated with placebo (GPP, n = 15), and gastroschisis pretreated with sodium bicarbonate (GPS, n = 15). The PS group was also divided into 2 subgroups to determine the biochemical differences between the amniotic and the allantoic fluid. Gastroschisis was created surgically at the 14th day of incubation. In GPS group, 8.4% NaHCO(3) solution (0.1 mL/100 mg/d) was instilled into the AAF for 4 days. RESULTS: A significant decrease in intestinal damage was observed both macroscopically and microscopically in the group GPS compared with the JG and GPP groups. CONCLUSIONS: Pretreatment with alkalization of AAF prevented intestinal damage because of gastroschisis. Alkalization could be a simple alternative for pretreatment with amniotic fluid exchange for human fetuses with gastroschisis.

Outcomes of one-stage techniques for proximal hypospadias repair.

OBJECTIVES: To evaluate the success of three preputial flap techniques in the one-stage correction of proximal hypospadias. METHODS: From 1993 to 1999, 43 children underwent one-stage proximal hypospadias repair using preputial flaps, which were performed by a single surgeon. Of the 43 patients, 21 (48.8%), 10 (23.2%), and 12 (27.9%) underwent tubularized island flap urethroplasty, double-faced tubularized island flap urethroplasty, and onlay island flap urethroplasty, respectively. The age range of the patients at surgery was 18 months to 14 years (mean 3.4). Dorsal plication was required for chordee repair in 12 patients (3 in tubularized island flaps, 3 in double-faced tubularized island flaps, and 6 in onlay island flaps). In addition to the dorsal plication, posterior dissection of the urethral plate without division was performed on 3 of the 6 patients with mild to severe chordee in the onlay island flap group. The incidence of complications requiring repeated surgery was evaluated for each group. RESULTS: The follow-up was 8 months to 7 years (mean 4.1 years). The overall complication rate was 90% for the double-faced tubularized island flap repair, 38% for the tubularized island flap repair, and 33% for the onlay island flap repair. Recurrent chordee was observed in 2 (66.6%) of the 3 patients who underwent onlay island flap repair with urethral plate dissection. CONCLUSIONS: The use of a tubularized island flap is suggested for one-stage repair of proximal hypospadias, especially in the patients with severe chordee. Because of the high complication rates, the double-faced tubularized island flap technique is not advocated. The onlay island flap may also be used for proximal hypospadias repair if mild chordee is present. Because of the high recurrent chordee rate, dissection of the urethral plate without division is not suggested in the onlay island flap technique.

Internal inguinal hernia in a 20-month-old boy.

The authors report on a 20-month-old boy with internal inguinal hernia. The patient was reoperated for clinical signs of intestinal obstruction after an incarcerated inguinal hernia repair. The diagnosis of internal inguinal hernia was proven by surgical exploration. This is the first internal inguinal hernia case reported in the literature and completely different from the atypical parainguinal hernias reported before.

White paper on herbal products. American College of Clinical Pharmacy.

Individuals increasingly are taking a more active role in their health care, and herbal products have emerged as a common choice among self-care therapies. Pharmacists are active participants in the care of patients who are taking herbal products. Currently, most pharmacists are not educated adequately about herbal products and other types of alternative medicine. Furthermore, good information about many of these products is not available. These combined factors present a challenge for pharmacists as they seek to provide optimal care and counseling to patients who use herbs or supplements. We recommend the following actions to place pharmacists in better positions as effective agents protecting public safety: Regulations should be implemented at a federal level to require basic levels of standardization and quality control in the manufacture of herbal products. Indexing terms in medical bibliographic systems should be expanded to target herbal products. Funding should be increased for scientific research evaluating herbal products. Pharmacy schools should include a competency statement in their curricula regarding herbal medicines. Continuing education in herbal products should be available and encouraged for all pharmacists. Pharmacists should approach the use of all therapeutic interventions with scientific rigor, whether they are traditional or complementary in nature. Patients will benefit as more information is known and widely disseminated. By actively embracing the responsibility for counseling individuals on the appropriate use of herbal products, pharmacists will become a recognized source of expert information in this rapidly growing area, yielding important improvements in the quality of care.

The split notochord syndrome with dorsal enteric fistula, meningomyelocele and imperforate anus.

A male infant was referred to our department because of lumbosacral meningomyelocele, dorsal enteric fistula and imperforate anus. The mother had received a parenteral drug containing estradiol benzoate and progesterone for inducing abortion in the first trimester. She also used an anal pomade containing triamcinolone and lidocaine-HCl during the pregnancy for hemorrhoids. Sigmoid end colostomy was performed after meningomyelocele repair. On abdominal exploration a wandering spleen was detected but no other anomalies. Two months later, an abdominoperineal pullthrough was performed, and the patient was discharged well after three weeks. Our case is the sixth that had split notochord syndrome associated with dorsal enteric fistula and imperforate anus. Additionally, penoscrotal transposition and wandering spleen were present in this case. To our knowledge, these associated anomalies have been extremely rare.

Ultrastructural and hormonal changes in the contralateral adrenal gland in unilateral adrenal gland ischemia: an experimental study in rats.

While it is well known that unilateral tissue ischemia may result in contralateral damage in some paired organs, there is no universally accepted mechanism to explain why these contralateral changes occur. The aim of the present study was to investigate the ultrastructural and hormonal changes that occur in the contralateral nonischemic adrenal gland after unilateral ischemia of an adrenal gland in a rat model. The animals were divided into four groups of four rats each; namely, a control group which received a sham operation without any ischemic insult, a 2-h ischemic group, a 4-h ischemic group, and an 8-h ischemic group. The left adrenal blood vessels were ligated in all ischemia groups and blood samples were taken for hormonal study 2, 4, and 8 h later, after which bilateral adrenalectomy was performed to determine the ultrastructural changes. The plasma concentrations of aldosterone and cortisol were determined by radioimmunoassays. There was an increase in both aldosterone and cortisol levels related to the duration of the ischemia, but the differences among the groups were not statistically significant. Contralateral ultrastructural damage such as heterochromatin in nuclei, mitochondrial degeneration, endoplasmic reticulum cisternal widening, increased lipid droplets, and lysosomes, were demonstrated electron-microscopically after unilateral adrenal ischemia.
