Physical examination showed Center Thoracic and erythematous skin with surrounding edema and abscess formation of the right biceps extending into (Dominik Abdominal the axilla, and tenderness to palpation of the right upper extremity (RUE). Labs were white blood cell Zampino) Compartment count 16.1 x103/uL with bands 26%, hemoglobin 12.4 g/dL, platelets 89 x103/uL and blood lactate 2.98 Syndrome mmol/L. Patient was admitted to telemetry for sepsis secondary to right arm cellulitis and abscess. Bedside incision and drainage was performed. Blood and wound cultures were drawn and patient was started on Vancomycin and Levofloxacin. On the third day of admission, patient became febrile, obtunded and had signs of systemic toxicity. Labs showed a worsening leukocytosis and lactic acidosis. CT RUE was consistent with complex fluid collection and with extensive gas tracking encircling the entire length of the right biceps brachii muscle. Surgical debridement was performed twice over the next few days. Blood cultures grew corynbacterium and coagulase negative staphylococcus; wound culture grew coagulase negative staphylococcus. Levofloxacin was switched to Aztreonam. Patient continued to deteriorate, went into renal failure, and was transferred to the ICU where he was started on vasopressors and bicarbonate drip. MRI RUE revealed severe myositis involving the biceps brachii, coracobrachialis and pectoralis minor muscles. Patient was transferred to another hospital for possible amputation of RUE. The patient’s condition continued to decline. Following extensive workup, patient was diagnosed with chest and abdominal compartment syndrome requiring decompressive exploratory laparotomy. Given the severity of his illness and poor prognosis, his family decided to proceed with comfort care. Patient expired few hours later. Necrotizing fasciitis and myositis (NF&M) is clinically indistinguishable from soft tissue infections (STI) because of its rarity and lack of classic symptoms. In one report, only 21 cases of necrotizing myositis were documented between 1900‐1985. While, only 4 cases out of 20,000 autopsies were established in a second report. In our patient, characteristic signs and symptoms initially led us to the diagnosis of cellulitis. However, one must always consider NF&M in the differential diagnosis when presented with uncharacteristic symptoms such as escalating muscle pain, skin changes, and systemic toxicity. An MRI of the affected extremity must be obtained for an early diagnosis. An early debridement along with broad‐spectrum antibiotic coverage is the key to a better outcome.

Zampino) Our patient was a 55‐year‐old male who presented from a rehabilitation facility for tachycardia. He recently was discharged from the hospital after being treated for motor vehicle accident. Chest X‐Ray on admission showed right lower lobe opacity. Due to his recent hospitalization, there was a concern for healthcare associated pneumonia and he was started on IV Vancomycin and Cefepime. On the day of admission, his platelet count was 276,000. After three doses of Vancomycin, his platelet count started to decrease while all other cell lineages remained intact. Over the next 4 days, his platelets were down to 56,000. Vancomycin was held at that time due to high suspicion of drug‐induced thrombocytopenia and within 48 hours of its discontinuation, the platelet count started increasing. All other causes of thrombocytopenia were ruled out. He was on Rivaroxaban for atrial fibrillation hence did not need heparin for DVT prophylaxis. Pantoprazole has also been associated with decrease in platelet numbers but was never held as the patient has been chronically taking it at home. Rarely Cefepime has been linked to thrombocytopenia in literature but it was held on the sixth day of admission, after the platelets had already begun to increase. A few facilities have the capability to test for antibodies against Vancomycin but we were unable to get access to such an amenity hence the diagnosis of Vancomycin‐induced thrombocytopenia (VIT) was made clinically and by exclusion. On the day of discharge, 5 days after discontinuation of Vancomycin, his platelet count was 213,000. Severe thrombocytopenia is a rare but potentially life‐threatening complication of Vancomycin therapy. The etiology is considered to be immunologically mediated as suggested by the presence of specific drug dependent IgG and IgM antiplatelet antibodies in most patients however other mechanisms have also been suggested in studies. Early diagnosis may be made in specialist centers through detection of antibodies however these tests are not standardized and currently inaccessible to most places. Hence any abrupt decline in platelet count should prompt investigation and clinical suspicion should be high. Our patient had no other known risk factors for the development of rapid thrombocytopenia. Use of the Naranjo adverse drug reaction probability scale indicated a probable relationship (score of 7) between thrombocytopenia and vancomycin therapy. Platelets usually return to pre‐treatment values after discontinuation of the drug and the median time required ranges from 4 to 17 days.

We present a case of anuric acute renal failure due to bilateral renal vein thrombosis from IVCF migration. 68 years old male with a past medical history of DVT, PE with IVCF 5 years ago, diabetes mellitus, hypertension, obstructive sleep apnea presented to the emergency department with severe back pain. The patient started to have severe lower back, present throughout the day, constant, nonradiating and associated with nausea and vomiting. The patient was noted to have anuria and worsening azotemia. The patient was started on hemodialysis. Further workup revealed extensive bilateral proximal DVT on Doppler ultrasound. Computerized axial tomography (CT) abdomen showed features of bilateral renal vein thrombosis in the context of IVCF transverse migration occluding both renal veins. Heparin drip was started. The patient underwent an angiogram with thrombectomy. His kidney function and urine output started to improve and the patient was taken off dialysis. Discussion: IVCF migration is a rare complication and was reported in a minimal number of case reports. A previous case report showed filter migrated to a suprarenal position inside IVC causing bilateral renal vein thrombosis causing acute renal failure. Our case showed migration of IVCF into a transverse position within the renal veins bilaterally resulting in the renal shutdown.

  • Chapter 26: Fluid, Electrolyte, and Acid-Base Balance
    Chapter 26: Fluid, Electrolyte, and Acid-Base Balance Chapter 26 is unusual because it doesn’t introduce much new material, but it reviews and integrates information from earlier chapters to cover 3 types of regulation: regulation of fluid volume, regulation of electrolyte (=ion) concentrations, and regulation of pH. • Outline of slides: • 1. Regulating fluid levels (blood/ECF) • Compartments of the body • Regulation of fluid intake and excretion • 2. Regulating ion concentrations (blood/ECF) • 3. Regulating pH (blood/ECF) • Chemical buffers • Physiological regulation • Respiratory • Renal 1 3 subsections to this chapter – we will cover the middle one only briefly. 1 Ch. 26: Test Question Templates • Q1. Given relevant plasma data, classify a patient’s possible acid-base disorder as a metabolic or respiratory acidosis or alkalosis that is or is not fully compensated. Or, if given such a disorder, give expected plasma pH and CO2 level (high, normal, or low). • Example A: Plasma pH is 7.32, CO2 levels in blood are low. What is this? • Example B: A patient’s plasma has a pH of 7.5. Explain how you could make an additional measurement to determine whether the cause of this unusual pH is metabolic or respiratory. • Example C: A patient’s plasma CO2 levels are very low, yet plasma pH is normal. How can this be? 2 Q1. Example A: (slight) metabolic acidosis. Example B: Measure the CO2 level in the plasma. If the high plasma pH is due to a respiratory problem, the CO2 concentration will be low. If the high pH is NOT due to a respiratory problem, the CO2 will not be low, and may be high if the person is undergoing respiratory compensation for a metabolic alkalosis.

  • The Electro-Physiology-Feeedback Measures of Interstitial Fluids
    INTERNATIONAL MEDICAL UNIVERSITY The elecTro-Physiology-Feeedback Measures oF inTersTiTial Fluids BY PROFESSOR OF MEDICINE DESIRÉ DUBOUNET IMUNE PRESS 2008 Electro-Physiology -FeedBack Measures of Interstitial Fluids edited by Professor Emeritus Desire’ Dubounet, IMUNE ISBN 978-615-5169-03-8 1 CHAPTER 1 THE ELECTRO-PHYSIOLOGY-FEEDBACK MEASURES OF INTERSTITIAL FLUIDS The interstitial liquid constitutes the true interior volume that bathe the organs of the human body. It is by its presence that all the exchanges between plasma and the cells are performed. With the vascular, lymphatic and nervous systems, it seems to be the fourth communication way of information's between all the cells. No direct methods for sampling interstitial fluid are currently available. The composition of interstitial fluid, which constitutes the environment of the cells and is regulated by the electrical process of electrochemistry. This has previously been sampled by the suction blister or liquid paraffin techniques or by implantation of a perforated capsule or wick. The results have varied, depending on the sampling technique and animal species investigated. In one study, the ion distribution between vascular and interstitial compartments agreed with the Donnan equilibrium; in others, the concentrations of sodium and potassium were higher in interstitial fluid than in plasma. The concentration of protein in interstitial fluid is lower than in plasma, and the free ion activities theoretically differ from those of plasma because of the Donnan effect. In spite of these differences, and for practical reasons only, plasma is used clinically to monitor fluid and electrolytes. The relation between plasma and interstitial fluid is important in treating patients with abnormal plasma volume or homeostasis.

  • Acid-Base Disorders Made So Easy Even a Caveman Can Do It
    ACID-BASE DISORDERS MADE SO EASY EVEN A CAVEMAN CAN DO IT Lorraine R Franzi, MS/HSM, RD, LDN, CNSD Nutrition Support Specialist University of Pittsburgh Medical Center Pittsburgh, PA I. LEARNING OBJECTIVES The clinician after participating in the roundtable will be able to: 1) Indicate whether the pH level indicates acidosis or alkalosis. 2) State whether the cause of the pH imbalance is respiratory or metabolic. 3) Identify if there is any compensation for the acid-base imbalance. II. INTRODUCTION Acid-Base balance is an intricate concept which requires an intimate and detailed knowledge of the body’s metabolic pathways used to eliminate the H+ ion. Clinicians may find it daunting to understand when first introduced to the subject. This roundtable session will demonstrate how to analyze blood gas levels in a very elementary manner so as to diagnose any acid-base disorder in a matter of minutes. The body is in a constant state of flux delicately stabilizing the pH so as to maintain its normalcy. In order to prevent untoward effects of alkalosis or acidosis the body has three major buffering systems that it uses to adjust the pH. They are: 1) Plasma protein (Prot-) 2) Plasma hemoglobin (Hb-) 3) Bicarbonate (HCO3-) The Bicarbonate-Carbonic acid system is the most dominate buffering system and controls the majority of the hydrogen ion (H+) equilibrium. Maintaining homeostasis when these acid-base shifts occur is vital to survival. Metabolic and respiratory processes work in unison to keep the H+ normal and static. II. ACID-BASE ABNORMALITIES The four principal acid-base imbalances are illustrated in Table 1.

    Austrian Syndrome: A Rare Triad Justin L. Guthier1, Rita Pechulis1; 1. Department of Medicine, Lehigh Valley Health Network, Allentown, PA, United States. Learning Objective 1: Increase awareness of a deadly clinical syndrome, rare now in a culture of pervasive antibiotic therapy Learning Objective 2: Recognize the association of pneumonia, endocarditis and meningitis seen with invasive pneumocccal bacteremia Case: A 64 year old male, with no medical history, presented in respiratory distress to the emergency department. The patient had not seen a doctor in twenty years and had been ill for three weeks with cough, fever and lethargy. The patient’s wife admitted the patient had a significant history of alcohol and tobacco use. On the day of admission, the patient was found lying on the floor nonverbal and disoriented. A chest x-ray found a right upper lobe infiltrate and an EKG revealed Afib with RVR. Early differential diagnosis included meningitis/encephalitis vs. CVA vs. sepsis. A lumbar puncture revealed hazy CSF, glucose <1, WBC 174 and neutrophils 86. The patient was admitted to the intensive care unit for management of VDRF, meningitis, pneumonia and rate control of Afib. The patient was initiated on broad spectrum antibiotics and dexamethasone. Microbiology results returned positive for pneumococcal urinary antigen, as well as blood cultures positive for s. pneumonia. Given the presence of disseminated bacteremia, the patient underwent TEE which revealed a mitral valve vegetation of 0.4 cm and a 0.3cm aortic valve vegetative strand. Since there was no evidence of aortic insufficiency and only mild mitral regurgitation, valve replacement was deferred and the patient was managed medically.

  • Arterial Acid–Base Status During Digestion and Following Vascular Infusion of Nahco3 and Hcl in the South American Rattlesnake, Crotalus Durissus

Arvedsen a,b, Johnnie B. Andersen a,b, Morten Zaar a,b, Denis Andrade b, Augusto S. Abe b, Tobias Wang a,b,* a Department of Zoophysiology, The University of Aarhus, Denmark b Departamento de Zoologia, Instituto de Biocieˆncias, UNESP, Rio Claro, SP, Brazil Received 17 May 2005; received in revised form 30 September 2005; accepted 2 October 2005 Available online 10 November 2005 Abstract Digestion is associated with gastric secretion that leads to an alkalinisation of the blood, termed the ‘‘alkaline tide’’. Numerous studies on À different reptiles and amphibians show that while plasma bicarbonate concentration ([HCO3 ]pl) increases substantially during digestion, arterial pH (pHa) remains virtually unchanged, due to a concurrent rise in arterial PCO2 (PaCO2) caused by a relative hypoventilation. This has led to the suggestion that postprandial amphibians and reptiles regulate pHa rather than PaCO2. Here we characterize blood gases in the South American rattlesnake (Crotalus durissus) during digestion and following systemic infusions of NaHCO3 and HCl in fasting animals to induce a metabolic alkalosis or acidosis in fasting animals. The magnitude of these acid–base disturbances À À 1 were similar in magnitude to that mediated by digestion and exercise. Plasma [HCO3 ] increased from 18.4T1.5 to 23.7T1.0 mmol L during digestion and was accompanied by a respiratory compensation where PaCO2 increased from 13.0T0.7 to 19.1T1.4 mm Hg at 24 h.

  • Respiratory Considerations in the Patient with Renal Failure
    Respiratory Considerations in the Patient With Renal Failure David J Pierson MD FAARC Introduction Physiologic Connections Between the Lungs and the Kidneys Diseases That Affect Both Lungs and Kidneys Wegener’s Granulomatosis Systemic Lupus Erythematosus Goodpasture’s Syndrome Respiratory Effects of Chronic Renal Failure Pulmonary Edema Fibrinous Pleuritis Pericardial Effusion Tuberculosis and Other Infections Pulmonary Calcification Urinothorax Sleep Apnea Anemia Respiratory Effects of Acute Renal Failure Hemodialysis-Related Hypoxemia How Critical Illness and Mechanical Ventilation Can Damage the Kidneys Summary Lung and kidney function are intimately related in both health and disease. Respiratory changes help to mitigate the systemic effects of renal acid-base disturbances, and the reverse is also true, although renal compensation occurs more slowly than its respiratory counterpart. A large number of diseases affect both the lungs and the kidneys, presenting most often with alveolar hemorrhage and glomerulonephritis. Most of these conditions are uncommon or rare, although three of them— Wegener’s granulomatosis, systemic lupus erythematosus, and Goodpasture’s syndrome—are not infrequently encountered by respiratory care clinicians. Respiratory complications of chronic renal failure include pulmonary edema, fibrinous pleuritis, pulmonary calcification, and a predisposition to tuberculosis. Urinothorax is a rare entity associated with obstructive uropathy. Sleep distur- bances are extremely common in patients with end-stage renal disease, with sleep apnea occurring in 60% or more of such patients. The management of patients with acute renal failure is frequently complicated by pulmonary edema and the effects of both fluid overload and metabolic acidosis. These processes affect the management of mechanical ventilation in such patients and may interfere with weaning.
