Partial Nephrectomy Due to Renal Cell Carcinoma in a Patient Who Was a Prior Kidney Donor: Pitfalls About Living Kidney Donation, Case Report, and Review of the Literature.

Cancer development in the remnant kidney in living kidney donors represents a challenging process in terms of patient management. Total nephrectomy is the preferred method for tumors exceeding 7 cm in size. In the case presented here, partial nephrectomy was preferred because the patient was a prior living kidney donor.

Recommendations for bariatric and metabolic surgical operations during the COVID-19 pandemic in Turkey.

The world has been struggling with the COVID-19 virus since December 2019. Turkey has also been battling with the virus since March 2019. While struggling with this unknown virus, we have postponed our new bariatric surgeries like most elective surgery.

Impact of weight loss on epicardial fat and carotid intima media thickness after laparoscopic sleeve gastrectomy: A prospective study.

Background And Aims: Cardiovascular disease (CVD) is one of the leading causes of mortality in obese patients. We aimed to investigate the influence of significant weight loss following laparoscopic sleeve gastrectomy (LSG) on carotid intima media thickness (CIMT) and epicardial fat thickness (EFT) which are the independent predictors of subclinical atherosclerosis.

Methods And Results: Patients were recruited for standard indications.

Changes in serum lipid levels after laparoscopic sleeve gastrectomy in morbidly obese dyslipidemic and normolipidemic patients.

Background: This study investigated the effect of laparoscopic sleeve gastrectomy (LSG) performed for morbid obesity on serum lipid levels of dyslipidemic and normolipidemic patients.

Methods: 141 patients who underwent LSG between September 2014 and January 2016 were included in the study.

Results: The patients' mean body mass index was 46.

Long-term Results of Living Donors in Simultaneous Kidney and Liver Transplantations.

Introduction: Because of the shortage of organs available for transplantation, living related sequential transplantation with the use of liver and a kidney from the same donor has emerged as a reasonable therapeutic alternative. However, there is insufficient literature about the complications that living donors experience after simultaneous kidney and liver transplantations.

Methods: From December 2001 to October 2009, 5 living donors provided simultaneous donation of livers and kidneys and 1 living donor donated first her kidney and then her liver.

One of the Rare Causes of Acute Abdomen Leading to Subileus: Jejunal Diverticulitis.

Background: Jejunal diverticulitis is one of the rare causes of acute abdomen generally seen in the elderly. Jejunal diverticulosis was defined as the herniation of the mucosa and the submucosa from the inside of the muscular layer of the bowel wall on the mesenteric side of the intestine.

Case Report: We presented the intraoperative and pathological findings of a 69-year-old male patient who had presented with complaints about abdominal pain, nausea, and vomiting and been operated upon due to subileus and peritonitis induced by large-sized jejunal diverticulitis, along with his computed tomography (CT) findings.

The diagnostic importance of evaluation of solid breast masses by sonoelastography.

Objective: The aim of this study was to determine whether the use of a scoring method by sonoelastography in solid breast masses is helpful in differentiating benign and malignant lesions.

Material And Methods: One hundred and eighty solid breast masses in 155 patients (147 benign, 33 malignant) were prospectively evaluated in a two-year period. For each lesion, B-mode sonography and sonoelastography images were obtained.

Unusual case of severe late-onset cytomegalovirus-induced hemorrhagic cystitis and ureteritis in a renal transplant patient.

Cytomegalovirus (CMV) infection is common in solid organ transplant recipients and accounts for the majority of graft compromise. Major risk factors include primary exposure to CMV infection at the time of transplantation and the use of antilymphocyte agents such as OKT3 (the monoclonal antibody muromonab-CD3) and antithymocyte globulin. It most often develops during the first 6 months after transplantation.

An unusual cause of small bowel perforation: apricot pit.

Ingestion of foreign bodies can be a common problem, especially among children, alcoholics, and psychiatric and senile patients. Foreign bodies with smooth edges usually do not pose significant problems, but a sharp foreign object that is not retrieved immediately may penetrate the wall and cause complications. Ingested foreign bodies usually pass the intestinal tract uneventfully, and perforation occurs in less than 1%.

Results of 4-year analysis of conversion from calcineurin inhibitors to mTOR inhibitors in renal transplant patients: single-center experience.

In this retrospective study, 83 patients were accepted. Mammalian target of rapamycin (mTOR) group consisting of 37 patients were converted from calcineurin inhibitors (CNI), and the control group included 46 patients (initially CNI-receiving patients). As a control-match of each mTOR inhibitor patient, the succeeding patient with transplantation who continued CNI therapy was chosen.

Tuberculosis in renal transplant recipients.

Background: Renal transplant recipients should be considered at high risk for development of Mycobacterium tuberculosis infection (tuberculosis, TB). TB is relatively more frequent among transplant recipients than general population, depending on its epidemicity in the geographic region. Clinical manifestations in this group of patients may be atypical and deserve aggressive investigations for diagnosis.

Qualitative and semiquantitative evaluations of solid breast lesions by sonoelastography.

Objectives: Our purpose was to determine whether the combination of a qualitative elasticity scoring method and a semiquantitative strain index method by sonoelastography is useful for differentiating between benign and malignant breast masses.

Methods: Seventy-eight lesions in 71 consecutive patients with solid breast masses (62 benign and 16 malignant) were prospectively included in this study. For each lesion, B-mode sonographic and sonoelastographic images were obtained.

Delayed complete gastric outlet obstruction due to a dinner fork: report of a case.

Ingestion of foreign bodies can be a common problem especially among children, alcoholics, psychiatric patients, and senile patients, but ingestion of a metallic dinner fork is uncommon. Foreign bodies with smooth edges usually do not pose significant problems, but a sharp foreign object that is not retrieved at the earliest may penetrate the wall and cause complications. Ingested foreign bodies usually pass the intestinal tract without problems, and perforation occurs in less than 1%.

What is the role of the abdominal perfusion pressure for subclinical hepatic dysfunction in laparoscopic cholecystectomy?

Background: Subclinical hepatic dysfunction after laparoscopic cholecystectomy (LC) has been described in the literature. However, this alteration is not encountered in all patients. In order to address this situation, a prospective study was conducted to investigate the effect of abdominal perfusion pressure (APP) on liver function tests after LC performed under constant intra-abdominal pressure (IAP).

Cytomegalovirus disease in renal transplant recipients: a single-center experience.

Unlabelled: Cytomegalovirus (CMV) disease is an important complication and an independent risk factor for acute rejection and recipient morbidity-mortality. The aim of this study was to review the results of CMV disease in renal transplant recipients.

Method: We have retrospectively analyzed CMV disease in 120 renal transplant recipients and recorded the demographic features, clinical manifestations, and immunosuppressive regimens.

Combined liver-kidney transplantation and follow-up in primary hyperoxaluria treatment: report of three cases.

Introduction: Primary hyperoxaluria type-1 (PH1) is an autosomal recessive disorder caused by impaired activity of the hepatic peroxisomal alanine-glyoxilate aminotransferase, which leads to end-stage renal disease (ESRD) and requires combined liver-kidney transplantation (CLKT). Herein, we have reported 3 children diagnosed with PH1 who received CLKT. CASE 1: A 4.

A renal transplant recipient with delayed gastric emptying in amyloidosis due to familial Mediterranean fever improved with erythromycin: a case report.

Patients with systemic amyloidosis often have symptoms related to impared gastrointestinal motility due to delayed gastric emptying, which results from autonomic nerve or smooth muscle infiltration with amyloid. There is no current report about gastric delaying secondary to amyloidosis due to familial Mediterranean fever. In this report, we have described a renal transplant recipient with delayed gastric emptying secondary to amyloidosis due to familial Mediterranean fever, which improved with erithromycin treatment.

Successful therapy with rituximab of refractory acute humoral renal transplant rejection: a case report.

Acute humoral rejection (AHR) is generally less responsive to conventional anti-rejection treatment with consequent allograft losses. Therapeutic options include antilymphocyte antibody (ATG), intravenous immunglobulin (IVIG), plasmapheresis, or immunoadsorption with protein A together with intensification of immunsuppression with a tacrolimus/mycophenolate mofetil combination. This report describes a transplant recipient who responded to rituximab therapy as treatment for steroid-, ATG-, IVIG-, and plasmapheresis-resistant AHR.

Vascular endothelial growth factor expression and vascularity in renal allograft biopsies.

Background: Vascular endothelial growth factor (VEGF) expression influences tubular repair and promotes angiogenesis. The aim of the present study was to determine the relation of VEGF expression and cortical vascularity with renal pathological changes and clinical parameters in allograft biopsies.

Materials And Methods: Sections from 50 renal allograft biopsies were evaluated by streptavidine-biotin immunohistochemistry by primary antibodies against VEGF and CD34.

Hyperuricemia influences chronic cyclosporine nephropathy.

Background: The observation that long-standing hyperuricemia is associated with chronic tubulointerstitial disease, afferent arteriolopathy, intrarenal vasoconstriction, and increased vascular resistance raises the hypothesis that hyperuricemia might contribute to chronic cyclosporine (CsA) nephropathy. The aim of the present study was to investigate the effect of hyperuricemia on chronic CsA nephropathy.

Methods: Patients who were treated with CsA-based immunsuppressive regimens and underwent a renal biopsy were enrolled in this case-control study.

Successful reuse of a transplanted kidney: 3-year follow-up.

The number of new transplantations has not kept pace with the ever-growing number of patients waiting for a kidney transplant, and there has been a growing shortage of deceased donor kidneys. Previously transplanted organs have been used to increase the donor pool. There is very little data about the reuse of a transplanted kidney.

Correlation of C0 and C2 levels with lipid profiles in adolescent renal transplant recipients in the early and late posttransplant periods.

Hyperlipidemia is a frequent complication after renal transplantation. Cyclosporine therapy is an important cause of hyperlipidemia. It is still controversial whether C0 or C2 is the most effective way to monitor blood cyclosporine concentrations to guide dosages.

Association of corticosteroids and factor V, prothrombin, and MTHFR gene mutations with avascular osteonecrosis in renal allograft recipients.

The mechanism of posttransplantation avascular osteonecrosis (AVN) is controversial. Besides an increased bone marrow pressure due to reduced blood supply, enhanced coagulation has been considered. We investigated the associations of factor V Leiden, prothrombin G20210A, and MTHFR C677T mutations as well as cumulative corticosteroid doses with AVN in renal allograft recipients.
