Eight patients are presented who demonstrate many of the pulmonary complications seen in the prune-belly syndrome. The patients are divided into two major groups: Group I includes pulmonary hypoplasia; Group II includes lobar atelectasis and pneumonia. The etiology, pathogenesis, and radiographic features of these complications are discussed. Pulmonary complications become more important as renal dialysis and transplantation spare more of these patients from an early uremic death. Prompt recognition of the type and the extent of pulmonary disease in patients with the prune-belly syndrome may lead to increased survival.

From 1958 to March 1987 we corrected 704 patients with pectus excavatum. The condition occurred more frequently in boys (544 patients) than girls (160 patients). In the majority of patients (86%), the defect was evident at birth or within the first year of life. Musculoskeletal abnormalities were identified in 133 patients (scoliosis, 107; kyphosis, 4; myopathy, 3; Poland's syndrome, 3; Marfan's syndrome, 2; Pierre Robin syndrome, 2; prune belly syndrome, 2; neurofibromatosis, 3; cerebral palsy, 4; tuberous sclerosis, 1; and congenital diaphragmatic hernia, 2). Sixteen patients had associated congenital heart disease. A family history of chest wall deformity was present in 37% of the cases and a history of scoliosis in 11%. Surgical correction was performed using a uniform technique for bilateral subperichondrial resection of the deformed costal cartilages and sternal osteotomy resecting a wedge of the anterior cortex and fracturing the posterior cortex. Anterior displacement was maintained with silk sutures closing the osteotomy defect. In 28 early cases, the sternum was secured by intramedullary fixation with a Steinman pin. All repairs were completed with a low complication rate (4.4%; pneumothorax, 11; wound infection, 5; wound hematoma, 3; wound dehiscence, 5; pneumonia, 3; seroma, 1; hemoptysis, 1; hemopericardium, 1). Six complications were associated with Steinman pin fixation (hemoptysis, seroma, hemopericardium, pneumothorax, 3). Major recurrence occurred in 17 patients (2.7%) and led to revision in 12. Satisfactory long-term results were achieved in the remaining 687 patients, with follow-up ranging from 2 weeks to 27 years. Mean follow-up was 4.3 years.(ABSTRACT TRUNCATED AT 250 WORDS)

An open research question when leveraging ontological knowledge is when to treat different concepts separately from each other and when to aggregate them. For instance, concepts for the terms "paroxysmal cough" and "nocturnal cough" might be aggregated in a kidney disease study, but should be left separate in a pneumonia study. Determining whether two concepts are similar enough to be aggregated can help build better datasets for data mining purposes and avoid signal dilution. Quantifying the similarity among concepts is a difficult task, however, in part because such similarity is context-dependent. We propose a comprehensive method, which computes a similarity score for a concept pair by combining data-driven and ontology-driven knowledge. We demonstrate our method on concepts from SNOMED-CT and on a corpus of clinical notes of patients with chronic kidney disease. By combining information from usage patterns in clinical notes and from ontological structure, the method can prune out concepts that are simply related from those which are semantically similar. When evaluated against a list of concept pairs annotated for similarity, our method reaches an AUC (area under the curve) of 92%.

De novo lupus nephritis (LN) is a rare complication in renal transplantation recipients. We present the clinical manifestations of de novo LN in a 12-year-old boy who received a cadaveric renal transplant. The cause of end-stage renal disease was prune belly syndrome with renal dysplasia. His immunosuppressive drugs included tacrolimus, mycophenolate sodium, and prednisolone. After 3 years of treatment, he developed nephrotic syndrome (NS) without other symptoms of systemic lupus erythematosus (SLE). The renal pathology of the transplanted kidney showed suspicious acute cellular rejection and LN World Health Organization class IV-G (A/C). Antinuclear antibody was positive, but anti-dsDNA and anti-Smith were negative. The serum complements were initially normal. Pulse methylprednisolone was given and the dosages of all immunosuppressive drugs increased; notwithstanding, his edema and hypoalbuminemia worsened. Repeated biopsy of the transplanted kidney was done. A full-house pattern was documented under immunofluorescent examination which confirmed LN WHO class IV-G (A/C) without evidence of rejection. He then developed macrophage-associated hemophagocytic syndrome and cytomegalovirus pneumonia. He ultimately developed pulmonary hemorrhage and died owing to severe pneumonia. De novo LN should be considered in renal transplant recipients with new onset of NS despite there not being any other clinical manifestations of SLE.
