Background and Objectives: According to a recent Cochrane systematic review, renal impairment can develop in 0-84% of childhood cancer survivors in the future. The renal function impairment in this patient group can be related to nephrectomy, nephrotoxic agents therapy, abdominal radiotherapy, and combinations of these treatment methods. In this study, in a population of patients after anti-neoplastic therapy, with particular emphasis on patients after Wilms' tumour treatment, we compared new substances which play role in the chronic kidney disease (CKD) pathogenesis (asymmetric dimethylarginine-ADMA, symmetric dimethylarginine-SDMA) with standard renal function markers (e.g., creatinine and cystatin C in serum, creatinine in urine, etc.) to assess the usefulness of the former. ⋯ Results: Both the eGFR1 and eGFR2 values were significantly lower in group 1 than in group 3 (eGFR1: 93.3 (83.1-102.3) vs. 116.5 (96.8-126.9) mL/min/1.73 m2, p = 0.02; eGFR2: 82.7 (±14.4) vs. 94.4 (±11.9) mL/min/1.73 m2, p = 0.02). Additionally, there were weak positive correlations between SDMA and creatinine (p < 0.05, r = 0.24), and cystatin C (p < 0.05, r = 0.32) and weak negative correlations between SDMA and eGFR1 (p < 0.05, r = -0.25), eGFR2 (p < 0.05, r = -0.24), and eGFR3 (p < 0.05, r = -0.32). Conclusions: The usefulness of ADMA and SDMA in the diagnosis of renal functional impairment should be assessed in further studies. eGFR, calculated according to equations recommended for children, should be used in routine paediatric practice.

Antiretroviral therapy (ART) can restore protective immune responses against opportunistic infections (OIs) and reduce mortality in patients with human immunodeficiency virus (HIV) infections. Some patients treated with ART may develop immune reconstitution inflammatory syndrome (IRIS). Mycobacterium avium complex (MAC)-related IRIS most commonly presents as lymphadenitis, soft-tissue abscesses, and deteriorating lung infiltrates. ⋯ Results: Neurological symptoms improved after plasmapheresis and intravenous immunoglobulin (IVIG) treatment. To our knowledge, this is the first reported case of CIDP due to MAC-related IRIS. Clinicians should consider MAC-related IRIS in the differential diagnosis of CIDP in patients with HIV infections following the initiation of ART.

Background and Objectives: Dentin grafts have osteoinductive and osteoconductive properties and are considered as an alternative to autogenous graft. This study evaluates the efficacy of autogenous mineralized dentin graft (AMDG) alone or with xenograft and compares it with those of various graft materials used in the treatment of intraosseous bone defects. Materials and Methods: The third incisor teeth of six sheep (2-3 years old) were extracted and AMDG was obtained. ⋯ No statistically significant difference was found regarding the rates of new bone formation between the D and D + X groups (p = 1.0) and the other groups at both time intervals (p > 0.05). Conclusions: Similar results observed in this study between groups A, D, X, A + X and D + X demonstrate that AMDG can be successfully used in the treatment of intraosseous bone defects. Further experimental and clinical studies are needed to be able to evaluate the effectiveness of dentin grafts in different types of indications.

Review Case Reports
Primary Non-Hodgkin Uterine Lymphoma of the Cervix: A Literature Review.
Introduction: Non-Hodgkin lymphomas (NHL) comprise 85% of the total lymphomas diagnosed, with the histological type of diffuse large B-cell lymphomas (DLBCL) being the most prevalent in adults. In about 40% of cases, the location is extranodal. Uterine cervix lymphomas of this type are extremely rare (0.5-1.5%) and represent a diagnostic challenge. ⋯ CHOP (Cyclophosphamide, Hydroxydaunorubicin (also called doxorubicin or adriamycin), Oncovin (vincristine), Prednisone or Prednisolone) polychemotherapy and radiotherapy were effective and resulted in tumour regression (from 3.4 cm to tumour disappearance, with the cervix returning to normal size). Conclusions: The uterine cervix lymphoma prognosis is more conservative than that for a nodal lymphoma, mainly due to a later diagnosis determined via immunohistochemistry. Chemotherapy is the main treatment.

Review Case Reports
Genital Prolapse in Pregnant Woman as a Presentation of Aggressive Angiomyxoma: Case Report and Literature Review.
Background: Aggressive angiomyxoma is a rare entity within mesenchymal cell neoplasms, especially in pregnant women. Its main characteristic is the ability to infiltrate neighboring structures and to recur. Case Presentation: We present the case of a pregnant woman who debuted with a genital prolapse in the second trimester of pregnancy. ⋯ Conclusions: Aggressive angiomyxoma is a benign neoplasm that should be considered in the differential diagnosis of pelvic tumors in women. In pregnant women, the vaginal route of delivery is not contraindicated as long as the tumor does not obstruct the birth canal. The definitive treatment is surgery, preferably performed in a second stage after delivery.
