Bronchial Mucoepidermoid Carcinoma

A 12-year-old boy with chronic respiratory complaints, including cough, exercise intolerance, and persistent wheezing, was referred to our hospital because of persistent symptoms under extensive asthma therapy. A standard radiograph of the chest detected very slight hyperinflation of the left lung with increased lung translucency (Figure 1). Computed tomography revealed a polypoid mass distally in the left main bronchus with a density around 55 HU and very slightly decreased attenuation of the left lung, probably due to secondary air trapping (Figure 2). Bronchoscopy confirmed this finding, and biopsy revealed the mass to be a low-grade mucoepidermoid carcinoma (Figure 3). A curative bronchial sleeve resection was performed with partial mediastinal lymphadenectomy. All lymph nodes were normal, and there is no recurrence to this date (one year). Adjuvant chemotherapy was not indicated

International consensus statement on the diagnosis and management of autosomal dominant polycystic kidney disease in children and young people

These recommendations were systematically developed on behalf of the Network for Early Onset Cystic Kidney Disease (NEOCYST) by an international group of experts in autosomal dominant polycystic kidney disease (ADPKD) from paediatric and adult nephrology, human genetics, paediatric radiology and ethics specialties together with patient representatives. They have been endorsed by the International Pediatric Nephrology Association (IPNA) and the European Society of Paediatric Nephrology (ESPN). For asymptomatic minors at risk of ADPKD, ongoing surveillance (repeated screening for treatable disease manifestations without diagnostic testing) or immediate diagnostic screening are equally valid clinical approaches. Ultrasonography is the current radiological method of choice for screening. Sonographic detection of one or more cysts in an at-risk child is highly suggestive of ADPKD, but a negative scan cannot rule out ADPKD in childhood. Genetic testing is recommended for infants with very-early-onset symptomatic disease and for children with a negative family history and progressive disease. Children with a positive family history and either confirmed or unknown disease status should be monitored for hypertension (preferably by ambulatory blood pressure monitoring) and albuminuria. Currently, vasopressin antagonists should not be offered routinely but off-label use can be considered in selected children. No consensus was reached on the use of statins, but mTOR inhibitors and somatostatin analogues are not recommended. Children with ADPKD should be strongly encouraged to achieve the low dietary salt intake that is recommended for all children

Is Autosomal Dominant Polycystic Kidney Disease Becoming a Pediatric Disorder?

Autosomal dominant polycystic kidney disease (ADPKD) affects 1 in 400 to 1,000 live births, making it the most common monogenic cause of renal failure. Although no definite cure is available yet, it is important to affect disease progression by influencing modifiable factors such as hypertension and proteinuria. Besides this symptomatic management, the only drug currently recommended in Europe for selected adult patients with rapid disease progression, is the vasopressin receptor antagonist tolvaptan. However, the question remains whether these preventive interventions should be initiated before extensive renal damage has occurred. As renal cyst formation and expansion begins early in life, frequently in utero, ADPKD should no longer be considered an adult-onset disease. Moreover, the presence of hypertension and proteinuria in affected children has been reported to correlate well with disease severity. Until now, it is controversial whether children at-risk for ADPKD should be tested for the presence of the disease, and if so, how this should be done. Herein, we review the spectrum of pediatric ADPKD and discuss the pro and contra of testing at-risk children and the challenges and unmet needs in pediatric ADPKD care.status: publishe

An Unusual Presentation of Congenital Esophageal Stenosis Due to Tracheobronchial Remnants in a Newborn Prenatally Diagnosed with Duodenal Atresia

Congenital esophageal stenosis due to tracheobronchial remnants is defined as an intrinsic stenosis of the esophagus caused by congenital architectural abnormalities of the esophageal wall. Although CES is present at birth, it remains asymptomatic till at the age of 4-10 months, when solid food is introduced. Here we present a case diagnosed in the neonatal period after urgent cesarean for an associated duodenal atresia complicated with perforation. There is a mutual association between duodenal atresia and congenital esophageal stenosis. When duodenal atresia is diagnosed, think of possible associated esophageal abnormalities, especially when duodenal atresia is complicated by gastric perforation prenatally.status: publishe
