Abstract
Carney complex (CNC) is an ultrarare disorder causing cutaneous and cardiac myxomas, primary pigmented nodular adrenocortical disease, hypophyseal adenoma, and gonadal tumours. Genetic alterations are often missed under routine genetic testing. Pathogenic variants in PRKAR1A are identified in most cases, while large exonic or chromosomal deletions have only been reported in a few cases. Our aim was to identify the causal genetic alteration in our kindred with a clinical diagnosis of CNC and prove its pathogenic role by functional investigation. Targeted testing of PRKAR1A gene, whole exome and whole genome sequencing (WGS) were performed in the proband, one clinically affected and one unaffected relative. WGS identified a novel, large, 10,662 bp (10.6 kbp; LRG_514t1:c.-10403_-7 + 265del; hg19, chr17:g.66498293_66508954del) deletion in the promoter of PRKAR1A in heterozygous form in the affected family members. The exact breakpoints and the increased enzyme activity in deletion carriers compared to wild type carrier were proved. Segregation analysis and functional evaluation of PKA activity confirmed the pathogenic role of this alteration. A novel deletion upstream of the PRKAR1A gene was proved to be the cause of CNC. Our study underlines the need for WGS in molecular genetic testing of patients with monogenic disorders where conventional genetic analysis fails.

Abstract
Abstract: Machine perfusion of marginal grafts might be a possible solution to organ shortage and a promising tool for reducing waiting list morbidity and mortality. In recent years, optimizing the circumstances of organ preservation prior to implantation via machine perfusion has become a hot topic of research. Machine perfusion offers a platform for organ reconditioning, assessment of cell viability and function, pharmacological preconditioning, prolongation of preservation time (ischemia time) and finally reducing graft injury. The objective of the new technology is to increase the pool of transplantable organs safely. Multicentric prospective studies have been evaluating the short and long term outcomes of different methods, however, several questions still remain unanswered. This review summarizes the recent advances in the field of machine perfusion, focusing on preclinical and clinical results. Machine perfusion seems to be a new milestone in the modern era of solid organ transplantation. Orv Hetil. 2018; 159(46): 1882–1890.

Abstract
Normothermic ex vivo kidney perfusion (NEVKP) represents a novel approach for graft preservation and functional improvement in kidney transplantation. We investigated whether NEVKP also allows graft quality assessment before transplantation. Kidneys from 30-kg pigs were recovered in a model of heart-beating donation (group A) after 30 minutes (group B) or 60 minutes (group C) (n = 5/group) of warm ischemia. After 8 hours of NEVKP, contralateral kidneys were resected, grafts were autotransplanted, and the pigs were followed for 3 days. After transplantation, renal function measured based on peak serum creatinine differed significantly among groups (P < .05). Throughout NEVKP, intrarenal resistance was lowest in group A and highest in group C (P < .05). intrarenal resistance at the initiation of NEVKP correlated with postoperative renal function (P < .001 at NEVKP hour 1). Markers of acid-base homeostasis (pH, HCO3- , base excess) differed among groups (P < .05) and correlated with posttransplantation renal function (P < .001 for pH at NEVKP hour 1). Similarly, lactate and aspartate aminotransferase were lowest in noninjured grafts versus donation after circulatory death kidneys (P < .05) and correlated with posttransplantation kidney function (P < .001 for lactate at NEVKP hour 1). In conclusion, assessment of perfusion characteristics and clinically available perfusate biomarkers during NEVKP allows the prediction of posttransplantation graft function. Thus, NEVKP might allow decision-making regarding whether grafts are suitable for transplantation.

Abstract
Normothermic ex vivo kidney perfusion (NEVKP) demonstrated superior results compared to hypothermic storage in donation after circulatory death (DCD) kidney transplantation. It is unknown whether an optimal perfusion time exists following hypothermic storage to allow for the recovery of renal grafts from cold ischemic injury. In a porcine model of DCD kidney autotransplantation, the impact of initial static cold storage (SCS) (8 h) followed by various periods of NEVKP recovery was investigated: group A, 8 hSCS only (control); group B, 8 hSCS + 1 hNEVKP (brief NEVKP); group C, 8 hSCS + 8 hNEVKP (intermediate NEVKP); and group D, 8 hSCS + 16 hNEVKP (prolonged NEVKP). All grafts were preserved and transplanted successfully. One animal in group D was sacrificed and excluded by postoperative day 3 due to hind limb paralysis, but demonstrated good renal function. Postoperative graft assessment during 8 days' follow-up demonstrated lowest levels of peak serum creatinine for intermediate (C) and prolonged (D) NEVKP (p = 0.027). Histological assessment on day 8 demonstrated a significant difference in tubular injury (p = 0.001), with highest values for group B. These results suggest that longer periods of NEVKP following SCS are feasible and safe for postponing surgical transplant procedure and superior to brief NEVKP, reducing the damage caused during cold ischemic storage of renal grafts.

Abstract
Horseshoe kidney is a fusion anomaly found in approximately one in 400-600 people. Due to vascular and ureteral variations, transplantation with a horseshoe kidney presents a technical challenge. In our case, the isthmus connected the upper poles and contained parenchyma. It consisted of three renal arteries, five veins collected to the inferior vena cava, and two ureters and pyelons. It was implanted en bloc to the left side retroperitoneally. During the early period, cellular and humoral rejection was confirmed and treated. For a urine leak, double J catheters were implanted into both ureters. Later, the first catheter was removed. Subsequently, urinary sepsis developed, necessitating graftectomy. The uncommon anatomy of ureters and antibody-mediated rejection (AMR) may both be factors for a ureter tip necrosis led to an infected urinoma. After other Hungarian authors, we also report a horseshoe kidney transplantation that was technically successful. However, after an adequately treated but severe acute humoral rejection, the patient developed sepsis, and the kidney had to be removed. We conclude that transplantation with horseshoe kidney is technically feasible but may increase the risk for urinary complications and resultant infections. Careful consideration of risk and benefit is advised when a transplant professional is faced with this option.

Abstract
INTRODUCTION Coexistence of psychiatric comorbidity is very common in patients hospitalized with somatic problems. Several studies have shown that comorbid dementia increases the length of stay (LOS) in hospitals. The literature is more contradictory in the case of anxiety disorders, substance-related disorders, mood disorders and delirium. AIMS Our aim was to explore the influence of psychiatric comorbidity on the average length of hospital stay and the related costs among geriatric patients treated in internal wards. METHODS The examination was conducted on two departments of internal medicine for 3 months on all admitted patients above 65 years. Four psychometric tests were carried out in the first three days after hospitalization as a screen for psychiatric comorbidity. RESULTS In the whole study group the incidence of a depression syndrome of various severity reached 56%. We have not identified any difference in LOS when the depressive and non-depressive groups were compared. 59% of the patients showed some degree of cognitive impairment. Mean LOS was 7.4 days longer among patient suffering in severe dementia than in the group showing no cognitive deficit. CONCLUSION Our results have demonstrated that of the investigated psychiatric comorbid conditions, an increased LOS is connected only with dementia. The degree of the cognitive impairment shows a positive correlation with the length of stay and the cost of medical treatment. Given the high incidence rate of affective syndromes, it can be assumed that comorbid depression increases the chance of admission to an internal medicine ward with some somatic complaints. This can be attributed to a larval stage of depression manifesting as somatic symptoms.

Abstract
PURPOSE Data on blindness and visual impairment in patients attending ophthalmology clinics at the Orleans regional hospital center serving a semi-rural area in France were prospectively studied to examine prevalence of visual impairment. MATERIAL AND METHODS Clinical data on 1,172 consecutive and different patients attending the ophthalmology department during half-days over a 3-month period were collected and analyzed using a computerized system. RESULTS Prevalence of visual impairment (20/30 or less in the better eye) was 3% in subjects under 60 years of age and rose to 13.7% and 35.9% for patients in the 60-79 age range and over 80 years respectively. For patients under 60, the prevalence of severe visual impairment (20/200 or less in the better eye) was 1.2% and rose dramatically in older patients: 5.8% and 14.6% in the 60-79 year old patients and the over 80 patients respectively. There was no significant difference in the prevalence of visual impairment by sex. Leading causes of severe visual impairment among patients aged 60 years or older were macular degeneration (40%), diabetic retinopathy (16.6%) and cataract (13.3%). The prevalence of irreversible severe visual impairment was 7.4% among patients 60years of age or older. CONCLUSION A large number of patients attending our ophthalmology clinic have severe visual impairment, particularly those over 60 years of age. Our findings are comparable with extrapolations for population-based studies in English speaking countries and can be used to evaluate the prevalence of visual impairment in French rural areas. As the population ages, need for eye health care becomes more and more evident. It is important to organize systematic visual examination in subjects aged 70 to 80 years and to implement educational programs as part of local national health care policies for helping the visually impaired.
