PE CAP
Tachypnea, increased or decreased tactile fremitus; dull or flat percussion reflecting consolidation and pleural fluid, respectively; crackles; bronchial breath sounds ; pleural friction rub
63
Diagnose CAP-want bc empiric tratment better for specific , also public safety implications
Chest radiography (need sensitivity and specificity not perfect from PE) - CT for postobstructive PNA or suspected cavitary disease - some radiographically patterns suggest an etiology (pneumatoceles suggest s aureus) Sputum samples must have WBC>25 and <10 squamous epithelial cells per high-power field to be appropriate for culture. The sensitivity of sputum cultures is highly variable; in cases of proven bacteremic pneumococcal pneumonia, the yield of positive cultures form sputum samples<50% Blood cultures are positive in 5-14% of cases, most commonly yielding s pneumoniae. Blood cultures are optional for most CAP pots but should performed for high risk pts (pts with chronic liver disease or asplenia) Urine antigen tests for S pneumiae and legionella pneumophila type 1 can be helpful PCR of nasopharyngeal swabs has become the standard for diagnosis of respiratory viral infection and is also useful for detection of many atypical bacteria Serology: a fourfold rise in titer of specific IgM antibody can assist in diagnosis of pneumonia due to some pathogens; however, the time required to obtain a final result makes serology of limited clincial utility
64
What are the two sets of criteria that identify pts who will benefit from hostpail care
Pneumonia severity index CURB-65
65
Complications CAP
Respiratory failure, shock, multiorgan failure, coagulopathy, and exacerbation of comorbid disease. Metastatic infection occurs rarely and requires immediate attention -lung abscess may occur in association with aspiration or infection from single CAP pathogen (P. Aeruginosa). Any significant pleural effusion should be tapped for diagnostic and therapeutic purposes.
66
Pleura effusion pH<7, glucose<2.2 LDH >1000 or if bacteria seen or cultured
Fluid should be drained, a chest tube is usually required
67
Follow up CAP
CXR abnormalities may require 4-12 weeks to clear. Pts should receive influenza and pneumococcal vaccines, as appropriate

176
Mycobacterium kansaii
Gram positive acid fast, obligate aerobes, facultative intracellular organisms, Pulmonary: upper lung cavitary disease Disseminated disease in immunocompromised
177
Microbiology TB
Caused by organisms of the mycobacterium TB complex, which includes M Tb, most common and important agent of human mycobacteria disease, and M Boris, which is acquired via ingestion of unpasteurized milk. M Tb is a thin aerobic bacillus that is neutral on gram staining but that nice stained is acid fast. It cannot be decolonized by acid alcohol bc th cell walls high content of molecules acids and other lipids
178

184
Risk factors for active TB
Recent acquisition, comobidity (HIV..), malnutrition, tobacco smoking, and presence of fibrotic lesions
185
Pathogenesis T
AFB that reach alveoli are ingested by macrophages. The bacilli impair phagosome maturation, multipl, lyse the macrophages, and spread to regional lymph nodes, reform which they may disseminate thought the body. Thesis initial stages of infection are generally asymptomatic and induce cellular and humoral immunity
186
2-4 weeks after Tb infection
A tissue damaging response resulting from delayed hypersensitivity destroys nonactivated macrophages that contain multiplying bacilli, and a macrophage activating response activates cells capable of killing AFB. A granuloma forms at the site of the primary lesion and at sites of dissemination. The lesions can then either heal by fibrosis or undergo further evolution. Despite helping, viable bacilli can remain dormant within macrophages or in necrotic material for years
187

Primary Tb disease
Middle and lower lobes. Heal spontaneously, and calcified nodule (GHON FOCUS) remains - transient hilar and paratracheal lymphadenopathy is common - in immunosuppressed pts and children, primary disease may progress rapidly to significant clincial disease, with cavitation, pleural effusions and hematogenous dissemination (military)
191
Military disease
Hematogenous dissemination
192
Adult type TB
Initially with nonspecific and insidious signs and symptoms such as diurnal fever, night sweats, weight loss, anorexia, malaise, and weakness - as progresses get cough, pursuant sputum with blood streaking, extensive cavitation may develop, with occasional massive hemoptysis following erosion of a vessel located int he wall of a cavity - disease is usually localized to the apical and posterior segments of the upper lobes and superior segments of the lower lobes

Painless swelling of cervical and supraclavicular nodes (scrofula) - nodes are discrete early on but can develop into a matter nontender mass with a fistulas tract - fine needle aspiration or surgical excision biopsy of the node is requires for diagnosis. Cultures are positive 70=80%.
196
Pleural TB
20% extrapulmonary, from hypersensitivity response to mycobacteria antigens or contiguous spread of parenchymal inflammation - pleural fluid is straw colored and exudative, with protein levels >50% of those in serum, normal to low glucose, and pH 7.3, and pleocytosis, the pleural concentration deaminase, of low, virtually excludes - empyema is uncommon from rupture of a cavity with many bacilli into the pleural space. In these cases, direct smears and cultures are often positive, and surgical drainage us usually required in addition to chemo
197
GU T
Local symptoms predominate and 75% have a CXR with previous or concomitant pulmonary disease. Occasionally identified only after severe destructive lesions of kidney have developed. - UA pyuria and hematuria with negative bacterial cultures - mycobacteria culture of three morning urine specimens is diagnostic 90%
198
Weight bearing joints T
Most common spinal T(Potts)-often involves two or more adjacent vertebral bodies; in adults , lower thoracic/upper lumbar vertebrae are usually affected. Disease spreads to adjacent vertebral bodies, later affecting the intervertebral disk and causing collapse of vertebral bodies in advanced . Paravertebral cold abscess
199
Meningitis T

215
Transmission leprosy
Nasal drops maybe
216
Clinical leprosy
Polar tuberculoid to polar lepromatous disease is associated with an evolution from asymmetric localized Manuel’s and plaques to nodular and infuriated symmetric generalized skin manifestations, an increasing bacterial loss and loss of M leprae-specific cellular immunity.
217
Incubacliniincubation leprosy
2-40 years, usually 5-7
218
Tuberculoid leprosy
At the less severe end of the disease spectrum, TT leprosy results in symptoms confined to the skin and peripheral nerves , - one or several hypopigmented macules or plaques with sharp margins that are hypesthetic and have lost sweat glands and hair follicles are present. AFB are few or absent - there is asymmetric enlargement of one or several peripheral nerves-most often the ulnar, posterior auricular, peroneal and posterior tibial nerves-associated with hypesthesia and myopathy
219
LL leprosy
Pts develop symmetrically distributed skin nodules, raised plaques and diffuse dermal infiltration that can cause leonine fancies, loss of eyebrows and lashes, pendulous earlobes and dry scaling - numerous bacilli are present in skin, nerves, and all organs except the lungs and CNE - nerve enlargement and damage are usually symmetric and due to bacillary invasions
220
Complications leprosy
Reactional states-immune mediated inflammatory states(can be deadly) -erythema nodosum -painful erythematous papules that resolve spontaneously in 1 week Extremities-neuropathy (insensitive to stuff, and LOSE distal digits as result), Eyes-CN palsies, legophthalmos and corneal insensitivity may complicate ...blindness Nerve abscess-urgent surgery

OSA history clues
Impaired daytime attention -MVA, diffulty with memory, sleepiness Snoring Witnessed apnea Mood alterations -obese patients with depression must be screened for OSA 1/4 have complaints of this
258
Clincial findings OSA
Obesity, large neck circumference (short road), nasal obstruction( talk weird, short airway polyps and stuf congested), enlarged tonsils, narrow oropharynx, macroglossia, micrognathia, retrognathia
259
Can non obese people get OSA. How diagnose OSA
Yup Sleep history from parter and patient, morning headaches, fat, postmenopausal women, Need ******polysomnography(measures respiratory events and hours of sleep to derive the apneahypopnea index, which is the average number of apnea and hypoapnea events per hour >5 per hour confirms OSA) for diagnosis, may get electroencephalogram for sleep staging and assessment to accurately diagnose.
260
Manage OSA goals
Improve daytime sleepiness and cognitive performance, prevent long term sequelae Improve mood and depressive symptoms, higher quality of life, lower incidence of traffic accidents, decrease daytime sleepiness Improved quality of life
261
Tools to manage OSA
Lifestyle modifications, CPAP
262
Long term sequelae
Patients with moderatesevere OSA are -four times more likely to die each year than non affected patients - 2.5 times more likely to develop cancer - four times more likely to have a CVA ——get serum TSHwith recent weight gain it may be elevated), chest x ray for heart failure, ECG for heart failure, COC secondary erythrocytosis can be a complication of severe OSA with hypoxemia, overnight oximetry , arterial blood gas to OHS),
263
Lifestyle modifications OSA
Obese? Lose 10% or more Avoid etOH and sedatives 3-4 hrs prior to bed Lateral decubitus sleeping position (keep airways from collapsing) Intranasal steroids/decongestants-can help congestion
264
When give CPAP
If symptoms persist after modifications Pneumatically props airway open -increased intraluminal airway presssure and FRC-after modifications Defer driving Continuous positive atrial airway pressure ,
265
What is don’t adjust to CPAP
Bi-level PAP (BiPAP) CPAP has one pressure level; BiPAP has separate pressures for inspiratory and expiratory phases...may improve comfort and adherence Bi level positive airway pressure nasal ventilation or auto titrations positive pressure devices that modify airflow pressure to a more comfortable level.
266
Oral device OSA
Mandibular assist device - can eliminate need for CPAP in mild/moderate cases - protrudes the jaw and/or holds tongue forward to prevent prolapse
267
Upper airway surgery OSA
If cant use CPAP, resection of enlarged obstructing tonsils may be beneficial , -get fibrosis and things retract and enlarge more Uvulopalatopharyngoplasty (UPPP)-Respect tonsils and adenoids, make small airway larger - aleviate obstruction of the hypoglossal space. - can remove obstruction to airflow - patient selection important-many co factors involved - most commonly done of a variety of surgical procedures to alleviate airway obstruction Variable success Do polysomnogram after surger or mandibular to see how it works
268
Obesity hypoventilation syndrome-fat bicarb 48(long term respiratory acidosis-lets try to compensate), non smoker, Hct up (RBC increased...reactive from hypoxemia), pulse ox down, edema, right parasternal lift, JVD, NON SMOKER probably not COPD
Pickwickian syndrome-fat boy breathing disorder Too much CO3 and too little oxygen Many have sleep apnea Sluggish , depressed Can mimic copD, but PFT demonstrate restrictive not obstructive 90% will have OSA Risk of HF, hard to get 890% pickwinian have OSA, but restrictive defect rather than Ondine curse-fell in love with man found out he was cheating so out curse on him so he was aware of his breathing so if he forgot he would die if sleep DIE
269

Why get dyspnea in COPD
Increased dead space-increased PaCO2 Altered V/Q relationship-hypoxemia Airflow obstruction-limits ability to meet increased demands Reduced mechanical advantage of the diaphragm -Hoover sign, accessory respiratory muscle use, paradoxical respiratory motion Diaphragm flat so when breath it contracts and rams together out in periphery rib cage gets pulled in paradoxically, Diaphragm doesn’t descend , get suck in rather than out What Hoover sign is-
296
Normally tidal flow volume loops expand in both directions during exercise. I’m emphysema, the decreased expiratory time results in more air trapping and increases the FRC, shifting the tidal flow volume loop curves to the left, a phenomenon called
Dynamic hyperinflation

Difference between interstitial pneumonia’s and idiopathic pulmonary fibrotis
Interstitial-inflammations Nd fibrosis pattern, it is believed that epithelial surface injury int he alveoli leads to spreading fibrotic change into the interstitial and vasculature (UIP, NSIP, BOOP/COP) Idiopathic-formof idiopathic DPLD. A diagnosis is important bc its poor prognosis. Dyspnea on exertion, exercise intolerance , dry cough, and crackles on inspiration. In typical cases, imaging shows lower lung zone and subpleural linear reticular markings, volume low, honeycombingand traction bronchiectasis. Histoplasma-UIP. Clincial course punctuated by acute declines due to exacerbation ofunderlying disease or overlay of infection , HF, or other comorbidity. Poor prognosis.

Pathophysiology pneumothorax
Primary spontaneous pneumothorax-absence of an underlying lung disease -tall thin men10-30 from rupture subpleural bless Secondary spontaneous pneumothorac-complication of disease , Traumatic pneumothorac-penetrating or blunt trauma Iatrogenic pneumothorac-follow procedures such as thoracentensis, pleural biopsy, subclavian or internal jugular vein catheter placement, percutaneous lung biopsy, bronchoscopy with transbronchial biopsy, positive pressure mechanical vent Tension p-penetrating trauma ,lung infection, cardiopulmonary resuscitation, positive pressure-pressure of air in pleural space exceeds ambient pressure throughout the respiratory cycle-check valve mechanism allows air to enter the pleural space on inspiration and prevents egress or air on expiration
548
Describe management pneumothorac
Smal-observation, supplemental oxygen Spontaneous primary-simple aspiration drain of air with small bore catheter small bore chest tube to one way Heinrich valve protect against tension pneumo Secondary, large, tension-ventilation mechanical (tube thoracostomy) under water seal drainage and suction applied until lung expands Smoke-stop it Thoracoscopy/open thoracotomy-recurrence of spontaneous, bilateral pneumothorac, failure of tube thoracostomy Pneumocystis pneumonia-recurrence so hard. No best approach....
