Predictive Factors of Renal Graft Failure in Tunisian Children and young adults: A Retrospective Study.

Introduction: Pediatric end-stage renal disease is a rare but severe condition that causes numerous complications and impairs the quality of life of children. Kidney transplantation is the therapy of choice in pediatric end-stage renal disease.

The Tunnelled Atrial Catheter: A Promising Solution for Vascular Capital Depletion in Dialysis despite Associated Thrombi.

Introduction: Longer survival in dialysis led to a higher incidence of vascular access complications and failure. With the limited access to kidney transplantation programs and peritoneal dialysis, exhaustion of vascular access for hemodialysis is an increasingly common situation. Among the available options, atrial tunneled dialysis catheter (ATDC) has been reported as an effective vascular access in this population.

Introduction: Sarcoidosis is a systemic granulomatosis that can be associated with large-scale physical and mental disability, affecting the health related quality-of-life (HRQoL) of patients.

Aim: To evaluate the HRQoL of tunisian patients with sarcoidosis and to identify the factors that influence it.

Methods: We conducted an analytical, cross-sectional study collecting 31 patients with sarcoidosis according to the ATS/ERS/WASOG criteria.

Recurrent Urolithiasis Revealing Primary Hyperparathyroidism in a Nephrology Department.

Background: Urinary lithiasis constitutes a recurrent pathology affecting a relatively young population. The risk of progression to chronic renal failure and the cost of treatment are the most important issues. Primary hyperparathyroidism (PHPT) is responsible for urolithiasis and nephrocalcinosis in 7% of patients, and it represents the 7th cause of urolithiasis in Tunisia.

Uncovering the Spectrum of Hemophagocytic Lymphohistiocytosis: A Nephrology Department's Analysis of 14 Cases.

Introduction: Hemophagocytic lymphohistiocytosis (HLH) is a disease of multi-organ dysfunction due to excessive immune activation causing widespread inflammation and tissue destruction. It is a severe condition associated with high morbidity and mortality. Early identification is crucial for prompt treatment.

An exceptional cause of polyuria-polydipsia syndrome in a 10-year-old boy.

Polyuria-polydipsia syndrome is a frequent symptom in pediatrics, primarily attributed to diabetes mellitus. In the context of diabetes insipidus, this syndrome can stem from central or nephrogenic factors. Sjögren's syndrome, an uncommon autoimmune disease in children, can affect multiple organs.

Primary Hyperoxaluria Type 1: Clinical, Paraclinical, and Evolutionary Aspects in Adults from One Nephrology Center.

Introduction: Primary hyperoxaluria type 1 (PH1) is a rare and inherited condition of urolithiasis. The aim of our study was to analyze clinical, paraclinical, and evolutionary aspects of PH1 in adult patients in our Nephrology department.

Methods: We conducted a retrospective single-center study between 1990 and 2021.

Decoding Hypercalcemia and Renal Stones in a Young Adult: Could it be Dent's Disease?

Dent's disease is a rare genetic kidney disorder characterized by proximal tubular dysfunction, nephrocalcinosis, recurrent nephrolithiasis, and chronic kidney disease. Hypercalcemia is a rare finding in this disease. In this report, we present a case of possible Dent's disease in a young adult male with hypercalcemia and chronic kidney disease.

Systemic lupus erythematosus presenting as lupus erythematosus tumidus and lupus nephritis: a case report.

Background: Lupus nephritis and lupus erythematosus tumidus (LET) are uncommon manifestations of systemic lupus erythematosus (SLE), and their coexistence as the initial presentation of SLE is exceedingly rare. Here, we report such a case, emphasizing the diagnostic challenges and therapeutic implications of this unusual association.

Case Report: A 38-year-old North African woman presented in Nephrology department with a history of lower extremity edema, fatigue, and weight loss of 3 kg in 4 weeks.

Multiple Myeloma in a Young Adult with Renal Involvement.

Multiple myeloma (MM) results from malignant plasma cell disorder. It represents approximately 10% of hematological malignancies and it is typically diagnosed in the elderly with a median age of 70 years and has a steep increase in incidence with advancing age. N Engl J Med.

Tuberculous tenosynovitis of the hand: A challenging diagnosis.

Tuberculous tenosynovitis of the hand is a very rare condition. Herein, we report the case of tuberculous tenosynovitis of the hand in a 32-year-old woman. We highlight the success of anti tuberculosis drugs alone without resort to surgical treatment.

[Type IVa2 urinary lithiasis and associated pathologies: About 3 cases].

Introduction: Urinary lithiasis is a very common condition. The morpho-constitutional analysis of urinary stones is important for etiological diagnosis. It guides the explorations and the specific management.

Thirty years of experience with anti-neutrophil cytoplasmic antibody glomerulonephritis in Charles Nicolle Hospital-Tunisia: a retrospective cohort study.

Introduction: antineutrophil cytoplasmic antibodies (ANCA) associated Glomerulonephritis (GN) is rare but a life-threatening disease especially, particularly in patients with advanced renal failure at presentation. This study aims to evaluate the epidemiological, clinical and histopathological features of renal involvement and investigate factors associated with ESRD.

Methods: patients with renal biopsy-proven ANCA associated glomerulonephritis were included retrospectively over a thirty years period.

Renal Amyloidosis: Epidemiological, Clinical, and Laboratory Profile in Adults from One Nephrology Center.

Background: Renal amyloidosis is one of the main differential diagnoses of nephrotic proteinuria in adults and the elderly. The aim of this study with the most important series in our country is to contribute to the epidemiological, clinical, and etiological study of the renal amyloidosis.

Methods: In a retrospective study carried out between 1975 and 2019, 310 cases of histologically proven and typed renal amyloidosis were selected for this study.

Gitelman syndrome, hypomagnesemia, and venous thrombosis: An intriguing association.

Among salt-wasting tubulopathies' complications, venous thrombosis is one of the rarest. We report a case of a young woman with Gitelman syndrome (GS). She presented a deep venous thrombosis in her leg and was treated with heparin with favorable outcomes.

[Left ventricular hypertrophy in hemodialysis patient: Prevalence, electrocardiographic, echocardiographic study and associated risk factors].

Background: Left ventricular hypertrophy is the most prevalent cardiac abnormality in hemodialysis patients. The diagnosis of this abnormality is possible by electrocardiogram and/or echocardiography. Our study aimed to assess the prevalence of left ventricular hypertrophy in hemodialysis patients and the accuracy of different electrocardiographic criteria.

No significant morbidity from recurrence cancer and no development of secondary type of cancers in pre-existing malignancies. We must be careful about risk of rejection.

[Emphysematous pyelonephritis and cystitis: An exceptional complication in a kidney transplant recipient].

Emphysematous pyelonephritis is a rare and severe infectious complication characterized by the presence of gas in the renal parenchyma, excretory cavities and surrounded tissues. It is due to the development of non-anaerobic gasifier bacteria. We report a new rare case of emphysematous pyelonephritis in a kidney transplant recipient, particular by its occurrence in a non-functional graft and its exceptional association with emphysematous cystitis.
