Our findings suggest that the combination of fetal and postnatal renal pelvic dilatation is able to increase the diagnostic accuracy for detecting infants who need a more comprehensive postnatal investigation for upper urinary tract obstruction.

Background:The purpose of this study was to integrate the available data published on leukaemic infiltration in the oral and maxillofacial region into a comprehensive analysis of its clinical manifestations, imaginological characteristics, management and survival.Materials and methods: An electronic search with no publication date restriction was undertaken in October 2020 in the following databases: PubMed, Web of Science, Scopus and Embase. Overall survival was calculated by survival analysis with the Kaplan-Meier test. A critical appraisal of included articles was performed using the Joanna Briggs Institute tool.Results: A total of 63 studies including 68 patients were selected for data extraction. The most common haematologic diagnosis was acute myeloid leukaemia (47%).The most affected individuals were 40 to 49 years old (20.9%). The male-to-female ratio was 1.2:1. The gingiva was the most affected site (37%). Swelling/mass/oedema (33.7%) and enlargement/hyperplasia/hypertrophy (25.5%) were the main clinical findings. Osteolytic lesions with bone destruction were the main imaginological characteristics among the reported cases. Follow-up was available for 36 patients.Overall, within the 21-month follow-up, the survival probability dropped to 14.3%. Conclusion:A considerable number of studies reported oral manifestations mainly in individuals with the acute form of leukaemia. Children and adults were affected, but the fifth decade of life was the most common. Dentists should be vigilant since these manifestations may be important for a diagnosis and for the monitoring of the treatment response and recurrence of haematological neoplasia.

BackgroundAntenatal hydronephrosis (ANH) affects ∼1–5% of pregnancies. The aim of this study was to develop a clinical prediction model of renal injury in a large cohort of infants with isolated ANH.MethodsThis is a longitudinal cohort study of 447 infants with ANH admitted since birth between 1989 and 2015 at a tertiary care center. The primary endpoint was time until the occurrence of a composite event of renal injury, which includes proteinuria, hypertension and chronic kidney disease (CKD). A predictive model was developed using a Cox proportional hazards model and evaluated by C-statistics.ResultsRenal pelvic dilatation (RPD) was classified into two groups [Grades 1–2 (n = 255) versus Grades 3–4 (n = 192)]. The median follow-up time was 6.4 years (interquartile range 2.8–12.5). Thirteen patients (2.9%) developed proteinuria, 6 (1.3%) hypertension and 14 (3.1%) CKD Stage 2. All events occurred in patients with RPD Grades 3–4. After adjustment, three covariables remained as predictors of the composite event: creatinine {hazard ratio [HR] 1.27, [95% confidence interval (CI) 1.05–1.56]}, renal parenchyma thickness at birth [HR 0.78(95% CI 0.625–0.991)] and recurrent urinary tract infections [HR 4.52 (95% CI 1.49–13.6)]. The probability of renal injury at 15 years of age was estimated as 0, 15 and 24% for patients assigned to the low-risk, medium-risk and high-risk groups, respectively (P < 0.001).ConclusionOur findings indicate an uneventful clinical course for patients with Society for Fetal Urology (SFU) Grades 1–2 ANH. Conversely, for infants with SFU Grades 3–4 ANH, our prediction model enabled the identification of a subgroup of patients with increased risk of renal injury over time.

Cheilitis glandularis (CG) is a rare inflammatory disease of unknown etiology that affects the minor salivary glands predominantly in the lower lip. In this article, we report the case of an 18‐year‐old black woman who presented with a deep suppurative type of CG in both lips. In addition, we performed a systematic literature review in five databases (PubMed, Scopus, Web of Science, Ovid, and Embase) to identify CG case reports or case series. A total of 360 references were retrieved in the electronic databases. Thirty‐four articles met the inclusion criteria, and six were retrieved through manual search, totaling 40 articles included in the systematic review. Thirty‐nine (68.4%) cases occurred in male individuals and 18 (31.6%) in female individuals. The mean age of affected individuals was 40.9 years. Different clinical manifestations ranging from no symptoms to discomfort, pain, swelling, erythema, eversion of the lip, dilated ductal openings, ulcers, and crust have been reported. Among the included CG cases, 41 affected exclusively the lower lip (71.9%). In four cases, the CG only affected the upper lip (7.0%). In 12 cases, the lesion affected both the lower and upper lips (21.1%). Different treatment modalities were adopted in the management of CG. Although the surgical treatment was indicated (42.1%), the conservative treatment with topical medications, as in the present case, resulted in resolution in 21.0% of cases.
