Background: The present study investigates the complications that may occur during long-term follow-up in patients aged 18 years and older undergoing living donor liver transplantation (LDLT) in our clinic because of fulminant hepatitis.

Methods: The study included patients aged 18 years and older with a minimum survival of 6 months who underwent an LDLT between June 2000 and June 2017. The demographic data of the patients were evaluated in terms of late-term complications.

Outcomes of Surgical Strategies for Living Donor Liver Transplantation in Patients With Portal Vein Thrombosis: A Cohort Study.

Background: Adequate portal flow to the liver graft is the requirement of a successful liver transplant (LT). Historically, portal vein thrombosis (PVT) was a contraindication for LT, especially for living donor LT (LDLT), demanding technically more difficult operations and advanced technique. In this study, the outcomes of patients with and without PVT after LDLT were compared.

Recommendations for Hepatitis B Immunoglobulin and Antiviral Prophylaxis Against Hepatitis B Recurrence After Liver Transplantation.

The combination of hepatitis B immunoglobulin and potent nucleos(t)ide analogs after liver transplantation is considered as the standard of care for prophylaxis against hepatitis B virus recurrence. However, the recommended doses, route of administration, and duration of HBIG administration remain unclear. Moreover, hepatitis B immunoglobulin-free prophylaxis with potent nucleos(t)ide analogs has shown promising disease outcomes in preventing hepatitis B virus recurrence.

Evaluation of the effects of Ankaferd haemostat application on bone regeneration in rats with calvarial defects: histochemical, immunohistochemical and scintigraphic study.

Background: Bone wax, a haemostatic agent, is widely used in craniospinal surgical procedures for a long time, in spite of controversial results regarding its negative influence upon bone regeneration. In this experimental study, the effects of Ankaferd Blood Stopper (ABS), as an alternative haemostatic agent, were evaluated through histochemical, immunohistochemical and scintigraphic studies.

Materials And Methods: The total of 30 adult female Wistar albino rats was randomly divided into three groups: intact control group (n = 10), bone wax group (n = 10), and ABS group (n = 10).

Hair Transplantation in Burn Scar Alopecia After Combined Non-Ablative Fractional Laser and Microfat Graft Treatment.

Background: Burn scar and alopecia on hair-bearing areas can severely affect the social life of patients. Unlike healthy skin, poor biological and mechanical properties of scar tissue in the recipient area can reduce the survival rate of hair graft following hair transplantation.

Objectives: The authors sought to determine if combined non-ablative fractional laser (NAFL) and microfat injection could improve the survival rate of hair grafts on post burn scar.

Treatment of Trichiasis by Releasing Follicle Roots of Eyelashes: A New Technique.

Trichiasis is an acquired condition in which eyelashes are misdirected toward the ocular surface, resulting in eye irritation and ocular morbidities. Different treatment modalities have been described, including surgical and non-surgical methods. The goal of this article is to present a novel technique for treatment of trichiasis, with a brief review of treatment options.
