Delta waves as a sign of cortical plasticity after full-face transplantation.

This study focused on detecting the reflections of healing and change in cortex activation in full-face transplantation and lesions patients on EEG activity. Face transplant patients have facial lesions before transplantation and, to identify pre-face transplant patients' brain activity in the absence of pre-transplant recordings, we used data obtained from pre-transplant facial lesion patients. Ten healthy, four facial lesion and three full-face transplant patients participated in this study. EEG data recorded for four different sensory stimuli (brush from the right face, right hand, left face, and left-hand regions) were analyzed using wavelet packet transform method. EEG waves were analyzed for standard bands. Our findings indicate significant change in the 2-4 Hz frequency range which may be a result of ongoing or previous cortical reorganization for face lesion and transplant patients. Alterations of the delta wave seen in patients with facial lesion and face transplant can also be explained by the intense central plasticity. Our findings show that the delta band differences might be used as a marker in the evaluation of post-transplant cortical plasticity in the future.

International consensus recommendations on face transplantation: A 2-step Delphi study.

Face transplantation is a viable reconstructive approach for severe craniofacial defects. Despite the evolution witnessed in the field, ethical aspects, clinical and psychosocial implications, public perception, and economic sustainability remain the subject of debate and unanswered questions. Furthermore, poor data reporting and sharing, the absence of standardized metrics for outcome evaluation, and the lack of consensus definitions of success and failure have hampered the development of a "transplantation culture" on a global scale. We completed a 2-round online modified Delphi process with 35 international face transplant stakeholders, including surgeons, clinicians, psychologists, psychiatrists, ethicists, policymakers, and researchers, with a representation of 10 of the 19 face transplant teams that had already performed the procedure and 73% of face transplants. Themes addressed included patient assessment and selection, indications, social support networks, clinical framework, surgical considerations, data on patient progress and outcomes, definitions of success and failure, public image and perception, and financial sustainability. The presented recommendations are the product of a shared commitment of face transplant teams to foster the development of face transplantation and are aimed at providing a gold standard of practice and policy.

Miracles of science: Birth after uterus transplantation.

AIM: The concept of regaining childbearing ability via uterus transplantation (UTx) motivates many infertile women to pursue giving birth to their own children. This article provides insight into maternal and neonatal outcomes of the procedure globally and facilitates quality of care in related medical fields. METHODS: The authors searched ISI Web of Science, MEDLINE, non-PubMed-indexed journals, and common search engines to identify peer-review publications and unpublished sources in scientific reference databases. RESULTS: The feasibility of the procedure has been proven with 46 healthy children in 88 procedures so far. Success relies upon dedicated teamwork involving transplantation surgery, obstetrics and reproductive medicine, neonatology, pediatrics, psychology, and bioethics. However, challenges exist owing to donor, recipient, and fetus. Fetal growth in genetically foreign uterine allograft with altered feto-maternal interface and vascular anatomy, immunosuppressive exposure, lack of graft innervation leading to "unable-to-feel" uterine contractions and conception via assisted reproductive technology create notable risks during pregnancy. Significant portion of women are complicated by at least one or more obstetric problems. Preeclampsia, gestational hypertension and diabetes mellitus, elevated kidney indices, and preterm delivery are common complications. CONCLUSIONS: UTx has short- and long-term satisfying outcome. Advancements in the post-transplant management would undoubtedly lead this experimental procedure into mainstream clinical practice in the near future. However, both women and children of UTx need special consideration due to prematurity-related neonatal problems and the long-term effects of transplant pregnancy. Notable health risks for the recipient and fetus should be discussed with potential candidates for UTx.

A Rare Case of Castleman's Syndrome Presenting with a Mass in the Bifurcation of the Celiac Trunk.

INTRODUCTION: Castleman's disease is an extremely rare disease in the abdomen region characterized by benign lymphoepithelial proliferation. CASE PRESENTATION: We report a case of a 63-year-old female who presented with abdominal pain. Abdominal CT Angio and dynamic contrast-enhanced abdominal MRI revealed a mass lesion showing markedly contrast enhancement, no vascular invasion sign, and diffusion restriction lesion in the truncus coelicus bifurcation region. The mass was surgically resected completely. Pathological evaluation showed a hyaline-vascular type of Castleman's disease. CONCLUSION: Castleman's disease should be kept in mind in the differential diagnosis of an isolated intra-abdominal mass.

An Oroauricular Fistula After Mandibular Osteosarcoma Resection.

Bone tumors are rare malignancies and osteosarcoma is the most common malignant bone tumor. However, only 6% of all osteosarcomas occur in the mandible and maxilla 1. The location of these tumors also presents a unique set of challenges during resection and repair when compared to long bone tumors.

Let-Down Rhinoplasty in Patients With Cleft Lip Nose.

BACKGROUND AND OBJECTIVES: Rhinoplasty in patients with cleft lip nose (CLN) deformity is challenging. Cleft lip nose deformity primarily affects the nasal tip, columella, nostrils, alar base, floor, and septum. The needs of patients with CLN are quite different from those of patients who undergo primary rhinoplasty. Recently, the dorsal preservation rhinoplasty technique has gained popularity. We applied this technique to patients with CLN deformity to obtain better aesthetic and functional results. PATIENTS AND METHODS: Ten consecutive patients with indication for primary CLN reconstruction underwent let-down rhinoplasty. Rhinoplasties were performed using either the closed or open approach, with costal cartilage grafts and full-thickness skin grafts. A rhinoplasty outcome evaluation questionnaire was used to assess the results. Moreover, the use of the same questionnaire in prior patients allowed us to compare results between our previous and new techniques. RESULTS: The study included 6 female and 4 male patients, with ages ranging from 18 to 25 years. Only 1 patient had a history of bilateral cleft lip. Seven patients had a history of left-sided cleft lip, and 2 patients had right-sided cleft lip. Open-approach let-down rhinoplasty with costal cartilage grafts and full-thickness skin grafts was performed in 8 patients, whereas closed-approach let-down rhinoplasty with costal cartilage grafts was performed in 2 patients. Columellar struts and affected-side onlay costal cartilage grafts were used in all patients. All patients reported being satisfied with the let-down rhinoplasty outcome, and none complained of functional problems. However, nostril symmetry was not observed in some patients, particularly in patients who underwent closed-approach rhinoplasty. CONCLUSIONS: Combining open approach, full-thickness skin graft, costal cartilage graft, and let-down rhinoplasty shows promising and satisfactory outcomes in patients with CLN. However, further studies are required to confirm this observation.

The Ozkan Technique in Current Use in Uterus Transplantation: From the First Ever Successful Attempt to Clinical Reality.

Uterus-related infertility affects 3-5% of all young women, including Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, hysterectomy, or severe Asherman syndrome. For these women with uterus-related infertility, uterus transplantation is now a viable option. We performed the first surgically successful uterus transplant in September 2011. The Donor was a 22-year-old nulliparous woman. After five failed pregnancy attempts (pregnancy losses), ET attempts were discontinued in the first case, and a search for underlying etiology was performed, including static and dynamic imaging studies. Perfusion computed tomography revealed an obstructed blood outflow, particularly in the left anterolateral part of the uterus. In order to correct blood flow obstruction, a revision surgery was planned. By laparotomy, a saphenous vein graft was anastomosed between the left utero-ovarian and left ovarian vein. Perfusion computed tomography performed after the revision surgery confirmed the resolution of venous congestion and a decrease in uterine volume as well. Following surgical intervention, the patient was able to conceive after the first embryo transfer attempt. The baby was delivered with cesarean section at 28 weeks' gestation due to intrauterine growth restriction and abnormal Doppler ultrasonography findings. Following this case, our team performed the second uterus transplantation in July 2021. The recipient was a 32-year-old female with MRKH syndrome, and the donor was a 37-year-old multiparous braindead woman due to intracranial bleeding. After the transplant surgery, the second patient experienced menstrual bleeding six weeks after the operation. Seven months after the transplant, in the first ET attempt, pregnancy was achieved, and she delivered a healthy baby at 29 weeks of pregnancy. Uterus transplantation from a deceased donor is a feasible option for treating uterus-related infertility. When confronted with recurrent pregnancy losses, vascular revision surgery via arterial or venous supercharging could be an option in order to deal with focal underperfused areas defined by imaging studies.

Facial Expression after Face Transplant: An International Face Transplant Cohort Comparison.

BACKGROUND: Assessment of motor function restoration following face transplant (FT) is difficult, as standardized, bilateral tests are lacking. This study aims to bolster support for software-based analysis through international collaboration. METHODS: FaceReader (Noldus, Wageningen, The Netherlands), a facial expression analysis software, was used to analyze posttransplant videos of eight FT patients from Boston, Massachusetts (range, 1 to 9 years after transplant), two FT patients from Helsinki, Finland (range, 3 to 4 years after transplant), and three FT patients from Antalya, Turkey (range, 6.5 to 8.5 years after transplant). Age-matched healthy controls from respective countries had no history of prior facial procedures. Videos contained patients and controls performing facial expressions evaluated by software analysis using the Facial Action Coding System. Facial movements were assigned intensity score values between 0 (absent) and 1 (fully present). Maximum values were compared with respective healthy controls to calculate percentage restoration. RESULTS: Of 13 FT patients, eight patients were full FT, five patients were partial FT, and two patients were female patients. Compared with healthy controls, the median restoration of motor function was 36.9% (interquartile range, 28.8% to 52.9%) for all patients with FT ( P = 0.151). The median restoration of smile was 37.2% (interquartile range, 31.5% to 52.7%) for all patients with FT ( P = 0.065). When facial nerve coaptation was performed at the distal branch level, average motor function restoration was 42.7% ± 3.61% compared with 27.9% ± 6.71% at the proximal trunk coaptation level ( P = 0.032). Use of interpositional nerve grafts had no influence on motor outcomes. CONCLUSIONS: Software-based analysis is suitable to assess motor function after FT. International collaboration strengthens outcome data for FT. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Rare Relationship Between the Right Hepatic Artery and Common Hepatic Duct in Living Donor Right Hepatectomy.

In living donor liver transplant, it is vital to perceive the hepatic artery anatomy and its variants. In the normal hepatic artery pattern, the common hepatic artery originates from the celiac artery to form the proper hepatic artery and gastroduodenal artery. The proper hepatic artery divides into right and left branches that supply the right and left lobes of the liver, respectively. Here, we report a rare variation of the right hepatic artery that was detected during a living liver right lobe hepatectomy. A 59-year-old man with alcoholic liver cirrhosis underwent living donor liver transplant. The patient's niece (a 47-year-old woman) volunteered to be a living donor. During the hilar dissection, we noticed that the anterior and posterior branches of the right hepatic artery passed through points anterior and posterior to the common hepatic duct, respectively. The right anterior hepatic artery and the right hepatic artery were divided separately. Although previously defined classifications have described anatomical variations of origin, branching, and course of hepatic artery, the topographical relationship of the anterior right hepatic artery and the posterior right hepatic artery versus the common hepatic duct has not been a matter of concern. Awareness must be maintained of this rare anatomical course of the right hepatic artery, especially in living liver right lobe donors. In the event of donors with rare variations, living donor liver transplant should be performed by an experienced team.
