Q

25
functional criteria for pneumonectomy
fev1 more 1.8 L fev1/fvc more than 0.5 normal Pco2 at rest
26
histology of lung carcinoid
small polygonal cells e eosinophilic cytoplasm.Highly vascular pink red color.
27
2 conditions associated e OSA
HTN DM 2 These can lead to stroke etc.
28
in chest drain what does these signify 1 bubbling on cough 2 fluid in tube swinging
1 air is draining 2 drain is in right place and working
29
radiotherapy vs chemotherapy induced pneumonitis
diffuse in chemo focal to radiotherapy site is radiotherapy pneumonitis
30
which lung disease is a contributory factor to OSA
COPD
31
how many apnea/hypoapnea episode are diagnositic of OSA during polysomnography
15 or more/hour
32
silica is toxic to what and predisposes to which disease
macrophages TB
33
effect of pulmonary AV malformations on tlco
reduced tlco dur to R to L shunt
34
which of following causes clubing lung abcess or copd
Lung abscess
35
what is a typical feature CTEPH
increased A a gradient on exercise.
36
role of pul rehabiliation in copd
increase exercise capacity reduce hosp admissions
37
indication of immunotherapy for allergy or anaphylaxis
patient cant refrain from exposure like his job etc.
38
feature of carcinoid that are other than carcinoid syndrome
1 recurrent hemoptysis 2 lobar collapse or recurrent lobar pneumonia carcinoids are typical for their central bronchial loacation kleading to obstruction of bronchi thus leading to collapse and lobar pneumonuia.also there are highly vascular leading to hemoptysis
39
which value of chloride in sweat is diagnostic of cystic fibrosis
more than 60 mmol/L.If value is bw 30 to 60 genetic testing for CFTR should be performed.
40
some rare diseases that cause granulomatous disease in lungs
berrylliosis [ causes simillar pictute to sarcoid] histoplasmosis histiocytosis X [occurs in young patients]
41
pysiology of IPF in relation to recoil and compliance
decrease compliance but increased recoil.as these are inversely related. also widening of Aa gradient on exercise.[desaturation on minimal effort etc]
42
patern of inheritance of familail PPH [6 percent case]
AD e incomplete penetrance
43
is there any role of PEFR in copd
yes.it can predict prognosis as smoking cessation halts the fall in pefr.but major role is in asthma where it can guide tx of acute asthma as it reflects flow rate in LARGER airways.
44
in good-pasture anti-gbm antibodies are directed against
a3 chain of type 4 collagen
45
causes of false positive anti gbm antibodies
inhaled oils,hydrocarbons and solvents PCP pneumonia in HIV.
46
any genetic component associated with mesothlioma
loss of material from chromosome 22 in mesothelioma cell lines.this region that is lost may code for some tumor supressor genes.
47
what are only tx options in asbestosis
stop smokin [50x risk of ca in combos] stop working in asbestos NO role of steroids or other drugs in asbestosis.
48
what is mendelson syndrome
pneumonia caused by aspiration stomach content in particular the gastric juice.Lead to BRONCHOSPASM and rapid onset pneumonia e MINIMAL sputum.seen in anesthesized pts with absent gag or during epilectic seizures.
49
which vitamin supplimentations are recomended in cystic fibrosis vit A or B12
if given the option choose ADEK fat soluble options.no significant role of b12
50
definite diagnosis of anerobic aspiration pneumonia
culture from direct specimen obtained either thru bronchoscopy or transcurtaneous route.remember kleibsiella is a gram negative AEROBE causing cavitatory lesions.
51
alogrithym for diagnostic pleural aspiration vs ct chest.which to perform first.
in case of CANCER lungs or pulmonary patholgy like ild,first perform CT in case of systemic diseases like nephrotic syndrome where effusion is not resolving and no chest signs are mentioned in the vingette,go ahead for pleural aspiration and analysis.
52
investigation of choice for UNILATERAL diaphragm paralysis
FLUROSCOPY e SNIFF TEST.parodoxical upward movement of paralysed side due to raised intradominal pressure.NOT for bilateral paralysis.
53
occupations associated with silicosis and asbestosis
ASBESTOSIS = Plumbers,electricians,engineers and shipyard workers. SILICOSIS = quartz,sandblasting,mining,foundery,pottery,slate workers,tunelling.
54
what is the typical stethoscope finding in case of bronchial cancer [ xray showing hilar mass]
WHISPERING PECTORILOQUY = signifies consolidation.
55
which finding will favour a diagnosis of ARDS
increased elastic recoil of lungs due to alvelor damage and subsequent loss of surfectan increaing surface tnesion and recoil.also eventually the lung compliance can decrease later as these are inversely related.Remember PAWP will be normal or decreased in contrast to HF.
56
most common blood biochemical finding in PCP
raised LDH
57
manifestation and typical feature of hepatopulmonary syndrome
in CLD there is reduced clearance of vasodilators like NO.These lead to p.vasodilation.Ultimately PAVM forms in the lower lobes causing R to L shunt secondary to increased angiogenesis. typical feature is platypnea-orhtodeoxia syndrome i.e reduced saturation on errect position as compared to lying supine.This is due to AVMs in the lower lobes as in standing position blood goes to lower lobes,there is R to L shunt in these lower lobes so lower oxygenated blood goes to blood and low saturations
58
most common sequale of sarcoidosis with BHL and erythema nodosum
Complete resolution without treatment.
59
what are the features of crytogenic pulmonary eosinophilia
no cause raised eosinophils systemic features like fever,weight loss,malaise asthma in 50 percent raised ESR tx is steroids.
60
investigation of choice for churgh starus
skin biopsy showing granlumatous arteriopathy lung or kidney biopsy
61
MDR TB
TB resistant to isoniazid and rifampicin with or without other drugs resistance.HIV is a risk factor. tx should be with 5 anti tb drugs to which person is susceptible.it should continue until sputum samples are negative.Than 3 drug tx for further 9 to 24 months after negative sputum.
62
typical feature of cryptogenic organizing pneumonia
migratory opacities/consolidations.
63
tx of radiation pneumonitis
no tx if mild. steroids if severe.
64
diagnosis of cough variant asthama [asthma e cough in the morning and on walking etc]
NOTHING.we will do pfts and spirometry but it will be normal as there is minimal bronchoconstriction.Ultimately a trial of TX is required to show reversible bronchoconstriction and symptomatic relief at the same time.
65
tx of hypercalcemia associated e sarcoidosis
Steroids.
66
causes of decrease VOCAL resonance
Pleural effusion pneumothorax empyema atelectasis
67
causes of increased vocal resonance
pneumonia fibrosis cancer
68
carrier frequency of Cystic fibrosis
1 in 25 in white populations
69
which investigation is best for lymph node for mediastinal involvement assesment in NSCLC
mediastinoscopy or PET scan. ct can miss.
70
alveolar structure is preserved in which common lung disease
Asthma
71
tlco in idiopathic pulmonary heimosiderosi
raised. characterized by occurence in young pts.pallor,lethargy,dry cough and occasional hemotypsis
72
when should running,contact sports and other things like blowing trumpet can restart
after 2 months. never scuba dive air travel after 1 week of resolution
