Stethoscope - Wikipedia, the free encyclopedia

The stethoscope is an acoustic medical device for auscultation, or listening to the internal sounds of an animal or human body. It typically has a small disc-shaped resonator that is placed against the chest, and two tubes connected to earpieces. It is often used to listen to lung and heart sounds. It is also used to listen to intestines and blood flow in arteries and veins. In combination with a sphygmomanometer, it is commonly used for measurements of blood pressure. Less commonly, "mechanic's stethoscopes" are used to listen to internal sounds made by machines, such as diagnosing a malfunctioning automobile engine by listening to the sounds of its internal parts. Stethoscopes can also be used to check scientific vacuum chambers for leaks, and for various other small-scale acoustic monitoring tasks. A stethoscope that intensifies auscultatory sounds is called phonendoscope.

Diagnosis and Management of Community-Acquired Pneumonia in Adults - American Family Physician

Community-acquired pneumonia is diagnosed by clinical features (e.g., cough, fever, pleuritic chest pain) and by lung imaging, usually an infiltrate seen on chest radiography. Initial evaluation should determine the need for hospitalization versus outpatient management using validated mortality or severity prediction scores. Selected diagnostic laboratory testing, such as sputum and blood cultures, is indicated for inpatients with severe illness but is rarely useful for outpatients. Initial outpatient therapy should include a macrolide or doxycycline. For outpatients with comorbidities or who have used antibiotics within the previous three months, a respiratory fluoroquinolone (levofloxacin, gemifloxacin, or moxifloxacin), or an oral beta-lactam antibiotic plus a macrolide should be used. Inpatients not admitted to an intensive care unit should receive a respiratory fluoroquinolone, or a beta-lactam antibiotic plus a macrolide. Patients with severe community-acquired pneumonia or who are admitted to the intensive care unit should be treated with a beta-lactam antibiotic, plus azithromycin or a respiratory fluoroquinolone. Those with risk factors for Pseudomonas should be treated with a beta-lactam antibiotic (piperacillin/tazobactam, imipenem/cilastatin, meropenem, doripenem, or cefepime), plus an aminoglycoside and azithromycin or an antipseudomonal fluoroquinolone (levofloxacin or ciprofloxacin). Those with risk factors for methicillin-resistant Staphylococcus aureus should be given vancomycin or linezolid. Hospitalized patients may be switched from intravenous to oral antibiotics after they have clinical improvement and are able to tolerate oral medications, typically in the first three days. Adherence to the Infectious Diseases Society of America/American Thoracic Society guidelines for the management of community-acquired pneumonia has been shown to improve patient outcomes. Physicians should promote pneumococcal and influenza vaccination as a means to prevent community-acquired pneumonia and pneumococcal bacteremia.

What is the diagnosis?

A 55 year old man had chest and abdominal discomfort after a long haul flight. The chest discomfort resembled his usually stable angina pectoris. On admission his heart rate was 90 beats/min and his blood pressure was 95/52 mm Hg. Electrocardiography showed T wave inversion in the inferolateral leads, compatible with ischaemia, although serum troponin and D-dimer tests were negative. His arterial blood gases, pH, and lactate were normal. What does the supine abdominal radiograph show and what sign suggests the diagnosis (fig 1⇓)?

An often forgotten cause of chest pain

A 66 year old white woman presented to the emergency department of a district general hospital with shortness of breath and chest pain, which radiated to her back. She had previously received antibiotics from her general practitioner for a presumed chest infection. Comorbidities included drug controlled hypertension. On examination she was tachypnoeic and hypertensive with a blood pressure of 170/90 mm Hg. No disparity in blood pressure was seen between her arms. Because clinical signs and plain chest radiography were suggestive of a left sided basal pneumonia with associated parapneumonic effusion (fig 1⇓), she received intravenous antibiotics.
