A gastric outlet thickened mucosal fold associated with cytomegalovirus infection in an extremely preterm infant managed by surgical resection

Online ahead of print.ABSTRACTNon-bilious vomiting in preterm neonates discharged from neonatal intensive care units is a common complaint and is often associated with benign conditions such as gastro-oesophageal reflux. A neonate of 27 weeks gestation who presented later with vomiting owing to gastric outlet obstruction is described. He was discharged at 11 weeks of age and required re-admission 1 week later. He had persistent non-bilious vomiting from 7 weeks of age, failure to thrive and metabolic alkalosis. Clinical examination demonstrated visible gastric peristalsis, and hypertrophic pyloric stenosis was suspected. Ultrasound of the gastric pylorus and upper gastro-intestinal contrast studies were negative. Exploratory laparotomy after failure of conservative management revealed a thickened mucosal fold in the gastric pylorus, which was excised. Histopathology demonstrated inclusion bodies which are pathognomonic of cytomegalovirus infection. He was treated with valganciclovir for 6 weeks and was asymptomatic and thriving well at follow-up. Gastric outlet obstruction can be one of the manifestations of CMV infection of the gastro-intestinal tract. Diagnosis can be confirmed only by histopathology.Abbreviations: BPD: bronchopulmonary dysplasia; CMV: cytomegalovirus; H&E: haematoxylin and eosin; IHC: immunohistochemistry; IHPS: infantile hypertrophic pyloric stenosis; NEC: necrotising enteroco...

Online ahead of print.ABSTRACTSystemic lupus erythematosus (SLE)-related arthritis has been traditionally defined as non-erosive and is therefore considered a minor manifestation requiring a mild treatment. However, the concept of non-erosive arthritis in SLE has been challenged with the advent of sensitive imaging techniques, such as high-resolution ultrasound with power Doppler or magnetic resonance. The application of these new imaging tools has demonstrated that up to 40% of SLE patients with joint involvement can develop erosive damage. Thus, this mo...
A 67-year-old woman with end-stage kidney disease on peritoneal dialysis, with diabetes, with atrial fibrillation treated with warfarin, and with Sjogren syndrome presented with firm subcutaneous nodules on her thighs and a large exquisitely tender erythematous lesion on her abdomen with a necrotic center (Supplementary Figure S1). Given her typical presentation and presence of multiple risk factors for calciphylaxis, this was the leading diagnosis, and sodium thiosulfate was started. Dermatologic biopsy was performed at one of the firm but nonnecrotic lesions, to confirm the diagnosis.
The study by Kronfli et al1 was a small retrospective study of patients using a left ventricular assist device (LVAD) who had undergone carotid duplex ultrasound evaluation. Given the increasing utility of LVADs and their hemodynamic effects, it seems prudent to study the criteria for arterial stenosis in such patients. It was observed that the peak systolic velocity was decreased and the end-diastolic velocity and velocity ratios were increased. There were also three different flow pumps: 21 with axial flow, 13 with centrifugal flow, and 2 with pulsatile flow.
We described and illustrated the technique of ultrasound-guided percutaneous proximal axillary artery (PAA) access and, secondarily, evaluated the versatility and safety of this approach in aortic and peripheral endovascular interventions.
