Long- and short-term adverse outcomes in hemodialysis (HD) have been associated with intradialytic hypotension, a common HD complication and significant cause of morbidity. It has been suggested that knowledge of absolute blood volume (ABV) could be used to significantly improve treatment outcomes. Different dilution-based protocols have been proposed for estimating ABV, all relying on the classic mono-exponential back-extrapolation algorithm (BEXP). In this paper, we introduce a dialysate dilution protocol and an estimation algorithm based on a variable-volume, two-compartment, intravascular blood water content kinetic model (VVKM)...

I thank R. Cabadas and J. Álvarez-Escudero (1). 1. Apologies accepted. 2. The statistical significance of the difference in proportions seems doubtful. 3. Although these small studies do not allow us to confirm the safety of endoscopist-directed propofol sedation, they deserve a short comment as they represent the best available level of evidence (RCTs) and are also informative. 4. Hypoxemia, hypotension and bradycardia are frequent and have no clinical consequences in most cases. 5. The authors started this chapter by stating "scientific opinions must be carefully based" (3); 6...

PURPOSE: A prolonged seated time after intrathecal injection of hyperbaric bupivacaine and morphine is related to the incidence of hypotension during Cesarean delivery, but results in a high incidence of pain during peritoneal closure. We conducted this study to determine the effect of the addition of intrathecal fentanyl on the relationship between seated time and hypotension and intraoperative analgesia requirements. METHODS: Women undergoing Cesarean delivery were randomized to receive an intrathecal injection of either 11...

PURPOSE: Low-dose fractionated radiation therapy (LDFRT) induces effective cell killing through hyperradiation sensitivity and potentiates effects of chemotherapy. We report our second investigation of LDFRT as a potentiator of the chemotherapeutic effect of induction carboplatin and paclitaxel in locally advanced squamous cell cancer of the head and neck (SCCHN). EXPERIMENTAL DESIGN: Two cycles of induction therapy were given every 21 days: paclitaxel (75 mg/m(2)) on days 1, 8, and 15; carboplatin (area under the curve 6) day 1; and LDFRT 50 cGy fractions (2 each on days 1, 2, 8, and 15)...

Zoledronic acid (ZA), an intravenous aminobisphosphonate, is prescribed widely for postmenopausal osteoporosis. It is a relatively safe drug but may cause adverse effects including acute phase reaction. Oral non-aminobisphosphonates are known to cause diarrhoea that is usually mild and self-limited. Intravenous amino-bisphosphonates are not known to cause diarrhoea. We describe a case of acute watery diarrhoea complicated by severe hyponatremia and hypotension following ZA infusion. The patient needed intensive care for four days...

Wissam Shalish, Francois Olivier, Hany Aly, Guilherme Sant'Anna
Albumin is one of the most abundant proteins in plasma and serves many vital functions. Neonatal concentrations vary greatly with gestational and postnatal age. In critically ill neonates, hypoalbuminemia occurs due to decreased synthesis, increased losses or redistribution of albumin into the extravascular space, and has been associated with increased morbidities and mortality. For that reason, infusion of exogenous albumin as a volume expander has been proposed for various clinical settings including hypotension, delivery room resuscitation, sepsis and postoperative fluid management...

BACKGROUND: Anaphylaxis is difficult to diagnose in the absence of skin or mucosal signs and symptoms. We report two cases of anaphylaxis under general anesthesia, in which the initial presentation was in the form of respiratory signs, followed by skin manifestations 10-15 min later. Diagnosis of anaphylaxis was delayed because skin symptoms were absent early on in the presentation. CASE PRESENTATION: In the first case, a 23-year-old male patient with jaw deformity was scheduled to undergo maxillary alveolar osteotomy...

Orthostatic intolerance is defined as the provocation of symptoms upon standing, commonly caused by neurogenic orthostatic hypotension (OH) and postural tachycardia syndrome (POTS), the etiology for which has not been fully uncovered yet. Many reports have described the occurrence of dysautonomia, orthostatic intolerance and POTS following febrile illness, presumably viral and post-vaccine. Furthermore, patients with dysautonomia have higher rates of autoimmune disorders such as Hashimoto thyroiditis and SLE...

Importance: Guidelines recommend assessing orthostatic hypotension (OH) 3 minutes after rising from supine to standing positions. It is not known whether measurements performed immediately after standing predict adverse events as strongly as measurements performed closer to 3 minutes. Objective: To compare early vs later OH measurements and their association with history of dizziness and longitudinal adverse outcomes. Design, Setting, and Participants: This was a prospective cohort study of middle-aged (range, 44-66 years) participants in the Atherosclerosis Risk in Communities Study (1987-1989)...

BACKGROUND: During abdominal surgery, traction of the mesenterium provokes mesenteric traction syndrome, including hypotension, tachycardia, and flushing, along with an increase in plasma prostacyclin (PGI2). We evaluated whether postoperative complications are related to mesenteric traction syndrome during esophagectomy. METHODS: Flushing, hemodynamic variables, and plasma 6-keto-PGF1α were recorded during the abdominal part of open ( n = 25) and robotically assisted ( n = 25) esophagectomy...

BACKGROUND: Survival for childhood acute lymphoblastic leukaemia surpasses 90% with contemporary therapy; however, patients remain burdened by the severe toxic effects of treatment, including asparaginase-associated pancreatitis. To investigate the risk of complications and risk of re-exposing patients with asparaginase-associated pancreatitis to asparaginase, 18 acute lymphoblastic leukaemia trial groups merged data for this observational study. METHODS: Patient files from 26 trials run by 18 trial groups were reviewed on children (aged 1·0-17·9 years) diagnosed with t(9;22)-negative acute lymphoblastic leukaemia between June 1, 1996, and Jan 1, 2016, who within 50 days of asparaginase exposure developed asparaginase-associated pancreatitis...
