    Abstract Appendicular mucocele (AM) is a rare and potentially malignant entity linked to obstructive dilatation of the appendix with an intraluminal accumulation of mucoid material. Most AM is asymptomatic or simulates acute appendicitis. We report an exceptional case of AM discovered in the face of hypokalemia and aggravation of chronic kidney disease (CKD) without diarrhea in an old man. Investigations led to the diagnosis of AM in its malignant form complicated by gelatinous ascites. We retained mucinous hypersecretion as the cause of hypokalemia and acute renal failure. Aggressive surgery and intraperitoneal chemotherapy corrected hydroelectrolyte imbalance.

    Abstract Background: The effect of tacrolimus (TAC) on oxidative stress after kidney transplantation (KT) is unclear. This study aimed to evaluate the influence of TAC trough levels of oxidative stress status in Tunisian KT patients during the post-transplantation period (PTP).
    Methods: A prospective study including 90 KT patients was performed. TAC whole-blood concentrations were measured by the microparticle enzyme immunoassay method and adjusted according to the target range. Plasma levels of oxidants (malondialdehyde (MDA) and advanced oxidation protein products (AOPP)) and antioxidants (ascorbic acid, glutathione (GSH), glutathione peroxidase (GPx), and superoxide dismutase (SOD)) were measured using spectrophotometry. The subjects were subdivided according to PTP into three groups: patients with early, intermediate, and late PT. According to the TAC level, they were subdivided into LL-TAC, NL-TAC, and HL-TAC groups.
    Results: A decrease in MDA levels, SOD activity, and an increase in GSH levels and GPx activity were observed in patients with late PT compared to those with early and intermediate PT (
    Conclusion: Our results have shown that in KT patients, despite the recovery of kidney function, the TAC reduced but did not normalize oxidative stress levels in long-term therapy, and the TAC effect significantly depends on the concentration used.

    Abstract Introduction: Type1 primary hyperoxaluria is an infrequent autosomal recessive metabolic disease characterized by the accumulation of calcium oxalate in the kidney, which leads to end stage renal disease. In fact, the diagnosis of this disease is mandatory in order to avoid graft loss.
    Aim: To assess the incidence of primary hyperoxaluria and to develop the diagnostic value of bone marrow infiltration by calcium oxalate in uremic stone former patients.
    Methods: This study was conducted on a cohort of stone former patients identified in the south of Tunisia over a period of 18 years. Baseline characteristics were recorded. Clinical and laboratory data were collected on chart review. Secondary forms of hyperoxaluria were excluded. Bone marrow aspirate was performed in uremic patients from this cohort because early hyperoxaluria was suspected. Diagnostic accuracy of this test relating to sensitivity, specificity, positive predictive value and negative predictive value were also calculated.
    Results: A cohort of 31 patients comprising 17 male patients and 14 female patients were identified. During this time of diagnosis, the patient's ages ranged from 9 to 57 years old and 22 of them (70%) unfortunately died. Bone marrow aspirate was safely done in 16 uremic patients. It was positive in 12 patients and negative in 4 patients. Sensitivity, specificity, positive predictive value and negative predictive value were respectively 85%, 100%, 100% and 50%.
    Conclusion: The bone marrow examination represents both an easy and a worldwide feasible solution for the diagnosis of oxalosis, which affords an early diagnosis.

    Abstract Purpose of review: Green nephrology is a movement whose aim is to find ways to reduce the environmental impact of kidney care. The question is of particular concern in this field since haemodialysis is one of the major contributors to waste generation, energy use and water consumption in healthcare. Although several ways for improving sustainability have been advocated, they are all context sensitive. This review aims to analyse the interventions that have been proposed to improve the ecologic sustainability and reduce the carbon footprint of nephrology care adapting to specific settings, and taking advantage of local expertise.
    Recent findings: Green hospitals are becoming a reality in several high-income settings, thanks to new building guidelines, with greater awareness of climate change and users' demands. Water saving is feasible, and is increasingly done, in different ways (improving hardware, reducing and adapting dialysate flows). Recycling noncontaminated plastic waste is feasible, but is still rarely performed. However, ecological transition has been slow even in high-income countries, while in low and middle-income countries lack of resources limit the ability to cope with the planet's urgent needs. Conversely, where man-power cost is low, some time-consuming tasks, such as separation of various components for recycling may be affordable. Theoretically, implementation of all clinical tasks aiming to avoid or retard dialysis, should be a priority.
    Summary: There is no single roadmap for achieving green nephrology. Each setting should start from those feasible interventions most in line with its specific needs and priorities.

    Abstract Peritonitis is an important cause of morbidity and technique failure in peritoneal dialysis. Herein, we report peritonitis related to Acinetobacter lwoffi in two patients on peritoneal dialysis. The first case is a 63-year-old patient treated by automated peritoneal dialysis admitted with abdominal pain. The peritoneal effluent White Blood Cells count consisted of 280 cells/mm3. Then culture identified a multisensitive Acinetobacter lwoffi. Treatment with ceftazidime and ciprofloxacin had been started. The control dialysate culture was sterile after three weeks. The second patient is a 59-year-old female admitted because of diffuse abdominal pain and cloudy dialysate. The peritoneal effluent White Blood Cells count consisted of countless leukocytes, with predominantly polynuclear and culture identified Acinetobacter lwoffi. He received intraperitoneal ceftazidim and amikacin for three weeks. The control dialysate was sterile. Acinetobacter lwoffi is a rare cause of peritonitis and it can be treated successfully with early recognition and appropriate antibiotic therapy based on culture instead of catheter removal.

    Abstract Purpose: The present study aimed to investigate for the first time the effects of melatonin (MEL) intake on oxidative stress and cellular damage during intradialytic exercise (IEX).
    Methods: Thirteen hemodialysis (HD) patients volunteered to participate in the current randomized crossover trial. Participants performed four HD sessions in four different conditions: (Exercise (EX)-MEL), (EX-Placebo (PLA)), (Control (C)-MEL), and (C-PLA). 3 mg of MEL or PLA were taken 60 min before starting exercise, or at the equivalent time in the C conditions. Blood samples were taken before HD (T0), immediately after the end of IEX (T1), 60 min after IEX (T2), or at the corresponding times in the C conditions to measure free radicals damage, antioxidant biomarkers, as well as biomarkers of muscle and liver damage.
    Results: Malondialdehyde and Advanced Oxidation Protein Products decreased in (C-MEL) (
    Conclusion: This pilot study is the first to show that MEL ingestion, alone or combined with IEX, could improve oxidant-antioxidant balance during HD.

    Abstract Introduction: We evaluated the effect of intradialytic concurrent (resistance-endurance) training combined with melatonin (MEL) supplementation on functional capacity, muscle strength, postural balance, and quality of life (QoL) in hemodialysis (HD) patients.
    Methods: Thirty-three HD patients were randomized into three groups: Exercise (EX)-MEL (n = 11); EX-Placebo (PLA) (n = 11) and Control (C)-PLA (n = 11). Participants included in the EX-MEL and EX-PLA groups were submitted to concurrent training for 12 weeks.
    Results: EX-MEL and EX-PLA improved functional capacity, muscle strength, QoL, and postural balance parameters in eyes open and eyes closed conditions. Parameters of postural balance in the dual task condition were improved only in EX-MEL. EX-MEL induced better results in some domains of QoL compared with EX-PLA.
    Conclusion: Intradialytic concurrent training induced beneficial effects on physical function, muscle strength, postural balance, and QoL in HD patients. MEL supplementation combined with intradialytic exercise lead to better improvements in postural balance and QoL.

    Abstract We aimed to describe the clinical and biological characteristics and the prognosis of patients presenting with an additional light chain (LC) band along with a complete monoclonal protein on immunofixation (IF).An 8-year descriptive study was conducted to assess all cases with confirmed monoclonal gammopathies (MG). We studied those with an entire M-protein with 2 bands of LC of the same isotype based on the results of IF. Data were collected from patients' files.Among 548 cases of MG, we found 32 cases (5.8%) with an additional LC band. We included 28 patients (5%) with a confirmed diagnosis of multiple myeloma (MM). The m/f ratio was 2.5 with a median age of 63 years [32-80 years]. All MM patients had anemia, 16 (57%) had renal failure, 14 (50%) had lytic lesions, 9 (32%) received hemodialysis, and 7 (25%) had hypercalcemia. The free-kappa-lambda ratio was abnormal in all cases: median = 0.07 [0.002-58.57]. The mean overall survival (OS) was 22 months ± 38.76.Fifteen MM patients (48%) received chemotherapy, and 7 (22%) autologous stem cell transplants (SCT). Patients who received SCT had an OS higher than those who received other treatments (p = 0.038). OS was low in patients with high β2microglobulin levels (rho = -0.791; p = 0.001), and abnormally low free-kappa-lambda ratio (rho = -0.852;p = 0.04).The presence of an additional LC band with a complete monoclonal protein seems to identify newly diagnosed MM patients with poor outcomes and frequent renal impairment.
