However, there are many mutations that have not yet been described in the literature. We describe the clinical case of a term newborn with appropriate weight to its gestational age, without perinatal background of interest that, at birth, presented macrocephaly, hypertelorism, low-set ears, prominent forehead, micrognathia, camptodactyly, bilateral cryptorchidism, inspiratory stridor with the cry, multifocal systolic murmur, wide anterior fontanel and hypotonia of mixed characteristics and in whom a deletion of the 1q44 cytoband and a pathogenic duplication in the 9q32q34.3 cytoband were detected. We perform a review of the literature. © BMJ Publishing Group Limited 2020. No commercial re-use. See rights and permissions. Published by BMJ.Young man with acute onset nausea, vomiting, joint pain, abdominal pain, fever and weight loss was found to have gait ataxia and positive B rucella titres. He deteriorated despite appropriate antibiotics and developed confusion and disorientation. Lumbar puncture revealed lymphocytosis with high protein and low glucose. MRI showed diffuse demyelination. Pulse steroids resulted in rapid clinical, biochemical and radiological recovery. © BMJ Publishing Group Limited 2020. No commercial re-use. See rights and permissions. Published by BMJ.A 73-year-old woman was referred to a tertiary centre with isolated splenic metastasis from previous pT1aNo stage 1a lung adenocarcinoma. The patient underwent a right lower lobe lobectomy and mediastinal lymph node dissection 2 years ago for invasive adenocarcinoma with no adjuvant therapy. An incidental finding of new splenic cyst was noted on surveillance imaging, which was fluorodeoxyglucose positive on positron emission tomography, and confirmed on cytology to be metastatic lung adenocarcinoma. After multi-disciplinary team’s review, the patient underwent splenectomy, with partial excision of diaphragm due to local infiltration. Her postoperative course was eventful, and was complicated by a simple fluid collection in the surgical bed (amylase negative), a left sided pneumonia and atelectasis and left sided pleural effusion, requiring antibiotics and radiological drainage of the abdominal and pleural collection. The patient recovered well and is currently doing well 9 months postoperatively with no evidence of recurrence or metastatic disease. © BMJ Publishing Group Limited 2020. No commercial re-use.

They allow symptom management with intermittent drainage without requiring overnight admission to hospital. However, little is known about their effectiveness in the treatment of pleural infections. Here, we present a case where an IPC is used in the therapeutic management of tuberculous empyema. The IPC enabled outpatient treatment, allowed the patient to return to work and reduced the cost of treatment and the risk of hospital-acquired complications. © BMJ Publishing Group Limited 2020.

Published by BMJ.The overall kidney survival among lupus nephritis patients has improved with currently used induction immunosuppression regimens of corticosteroids and either cyclophosphamide or mycophenolate mofetil; however, there still remains a significant number of lupus nephritis patients who do not achieve remission with these regimens. Investigators have looked at other immunosuppressive regimens for lupus nephritis, and there has been interest in the use of calcineurin inhibitors in this regard. Calcineurin inhibitors are potentially an attractive option because of their established ability to inhibit T cell function, attenuate proteinuria through non-immunologic means, and their safety in pregnancy and lactation. In this review, we discuss the findings and limitations of selected trials that evaluated the use of calcineurin inhibitors in the treatment of lupus nephritis, either with corticosteroids alone or as a component of multitarget therapy when combined with mycophenolate mofetil. There may be a role for calcineurin inhibitors among patients with heavy proteinuria, as well as younger patients with refractory lupus nephritis. The multitarget therapy trials reveal higher rates of remission compared with mycophenolate mofetil alone and cyclophosphamide; however, some trials highlight the possibility of more infectious adverse events. We discuss the need for further study of calcineurin inhibitors in more diverse patient populations and the need for trials with longer follow-up with “hard” endpoints beyond proteinuria reduction, such as worsening CKD or repeat protocol biopsies, given the calcineurin inhibitors ability to reduce proteinuria non-immunologically and thus increased rate of relapse when the drug is tapered. While there may indeed be a space for calcineurin inhibitors to help increase remission rates in lupus nephritis patients, more work is needed to help address the questions the studies available to date have yet to answer. selleck Copyright © 2020 by the American Society of Nephrology.BACKGROUND AND OBJECTIVES Residual kidney function is important to the health and wellbeing of patients with ESKD. We tested whether the kidney clearances of proximal tubular secretory solutes are associated with burden of uremic and heart failure symptoms among patients on peritoneal dialysis with residual kidney function. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We enrolled 29 patients on incident peritoneal dialysis with residual urine output >250 ml daily. We used targeted liquid chromatography-mass spectrometry to quantify plasma, 24-hour urine, and peritoneal dialysate concentrations of ten tubular secretory solutes. We calculated the kidney and peritoneal dialysis clearances of each secretory solute, creatinine, and urea, and we estimated a composite kidney and peritoneal secretion score. We assessed for uremic symptoms using the Dialysis Symptom Index and heart failure-related symptoms using the Kansas City Cardiomyopathy Questionnaire. We used linear regression to determine associations of composite secretory solute clearances and GFRurea+Cr with Dialysis Symptom Index symptom score and Kansas City Cardiomyopathy Questionnaire summary score.
