Quality of dictated feedback associated with SIMPL operative assessments of pediatric surgical trainees

BackgroundSIMPL is a workplace-based operative performance assessment tool which allows for dictated feedback (DF). To better understand the value of DF, we sought to characterize the type and quality of DF generated during SIMPL evaluations.MethodsThematic analysis of DF from SIMPL assessments between June 2017 and December 2018 at a single pediatric surgery fellowship program was performed. Comments were categorized as specific, encouraging or corrective. Categories were combined to determine DF quality as effective, mediocre or ineffective.ResultsOf 781 SIMPL assessments (21 faculty, 5 trainees), 451 (57%) had DF. Most comments were encouraging (93%) and specific (65%). Only 21% were corrective, 17% had entrustment features, and 8% had an explicit learning plan. Feedback quality was deemed mediocre (45%), ineffective (33%) and effective (21%).ConclusionSIMPL dictated feedback was mostly encouraging and specific. To improve quality, feedback should incorporate learning plans as well as corrective and entrustment features.     

Early nephrectomy in neonates with symptomatic autosomal recessive polycystic kidney disease

IntroductionAutosomal recessive polycystic kidney disease (ARPKD) is a rare cause of renal failure with a highly variable clinical course. Patients who are symptomatic early in life frequently require early nephrectomy and peritoneal dialysis. In these patients there are little data to guide clinicians on whether to select unilateral nephrectomy or bilateral nephrectomy at the initial operative intervention. We review our experience with this disease process.MethodsA retrospective review was performed of 11 patients at our institution with ARPKD symptomatic within the first month of life. Charts were reviewed for relevant clinical data, and patients were divided into groups based on undergoing either unilateral or bilateral nephrectomy at their initial intervention. The decision for unilateral versus bilateral nephrectomy was decided by the clinical team without any available guidelines.ResultsOf the 11 patients reviewed, two patients died within the first two weeks from other complications. The remaining 9 all required nephrectomy, with 5 undergoing synchronous bilateral nephrectomy, and 4 undergoing initial unilateral nephrectomy. All four patients required removal of their contralateral kidney, a median of 25.5 days later. There was no difference in mortality, ventilator free days, or time to full feeds between the two groups, although the group undergoing initial unilateral nephrectomy had more TPN days than their counterparts (28 vs 17 days, p = 0.014).ConclusionsIn our cohort, there were few significant differences between the groups based on choice of initial unilateral or bilateral nephrectomy, and all children ultimately required removal of both kidneys. These data suggest that anesthetic exposures and other clinical outcomes might be optimized by initial bilateral nephrectomy.Level of evidenceIII.     

Staphylococcus lugdunensis pulmonary valve endocarditis in a patient on chronic hemodialysis

We describe a case of Staphylococcus lugdunensis pulmonary valve endocarditis in a 65-year-old woman on chronic hemodialysis and provide a review of previously reported cases. The patient presented with fever and altered mental status, but had no other localizing symptoms or signs; coagulase-negative staphylococcus (subsequently identified as S. lugdunensis) was isolated from two sets of blood cultures. Transthoracic and transesophageal echocardiograms showed a large (2.3 x 3.1 cm) vegetation on the pulmonary valve with moderate valvular insufficiency. The patient was treated with 6 weeks of antibiotic therapy and is stable 4 months following the completion of therapy; no surgical intervention was performed. Of the 28 previously reported cases of S. lugdunensis endocarditis, only 1 had previously survived with medical therapy alone. This is the 3rd case report of S. lugdunensis endocarditis in a patient on hemodialysis; the presumed portal of entry in this and previously reported cases was the vascular access device. Endocarditis due to this organism is characterized by a high mortality, rapid tissue destruction, and a predilection for native valves. Because the clinical outcome is much more favorable with valvular replacement, speciation of the organism assumes great importance in defining the therapeutic approach. Copyright Copyright 1999 S.

The cancer patient with chronic pain due to herpes zoster

Postherpetic neuralgia (PHN) is the most common complication of herpes zoster, and as such has been an area of extensive medical research for the past three decades. The patients at highest risk for PHN include those older than 50 years, those with severe acute cases of zoster, and those with shingles in a trigeminal distribution. As persons with malignancy are at a high risk for developing zoster itself, PHN is a complication that will be faced by many of these patients and their caregivers. This article reviews the available treatments and preventative measures for this debilitating condition.

Altered expression of progesterone receptors in testis of infertile men

Progesterone has been implicated in the process of spermatogenesis. This study aimed to investigate the association of progesterone receptor (PR) expression with spermatogenesis in the testis of infertile men. PR mRNA and protein were assessed by in-situ hybridization and immunohistochemistry in testicular biopsies obtained from 18 infertile men. The extent of spermatogenesis was assessed by Johnsen scoring. None of the patients included in the study had Yq microdeletions. PR expression was almost undetectable in all the testicular sections displaying Sertoli cell only (SCO) or arrest at spermatogonia. Weak cytoplasmic expression was observed in biopsies showing arrest at different stages of meiosis. In biopsies displaying spermatogenesis up to the round spermatid stages, PR expression was observed in both nucleus and cytoplasm of different cell types at intensity lower than that detected in normal biopsies. Normal PR expression was observed in biopsies demonstrating hypospermatogenesis. In biopsies showing mixed phenotypes, the tubules with SCO or spermatogonia arrest showed absence of PR expression; normal PR expression was observed in adjacent tubules showing complete spermatogenesis. Semi-quantitative assessment of PR expression and Johnsen scores in the testicular biopsies of infertile men demonstrating different phenotypes indicated a direct relationship between PR expression and extent of spermatogenesis.
