He is in addition a chronic fastb all(prenominal) compartment for the erstwhile(prenominal) 40 old age who smokes well-nigh 20 sticks of cig bettes a day.Mr TLT presented with shortness of breath which progressively change magnitude in severity for the past 4 age. The shortness of breath was associated with a wheeze. in that respect was in like manner coughing up with production of mucoid languor. The dyspnoea occurred after an episode of fastness respiratory bundle transmission system.Mr TLT has been having intermittent chronic cough associtaed with mucoid sputum for the past 3 geezerhood. He has also been having opinionated inanimateness for the past 1 year especially on motion. He has not sought treatment prior to this admission.On physical examination, Mr TLT was tacypnoiec with a respiratory pace of 28 breaths per minute. at that place was no cyanosis. Repiratory system examination showed engage of accesory muscles as well as ontogenesisd anterior posterior diameter of the agency and reduced cricosternal distance. On auscultation, vesicular breathing was hear with generalised rhonchi and coarse early inspiratory crepitations at the lower geographical zone of both lungs. The cardiovascular system examination was normal. in that location were no other abnormalities on physical examination.Investigations through include chest plain radiograph which showed a hyperinflated chest, tubular heart and absence of vascular markings at the peripheries.

He had been diagnosed with hypertension for the past one year and is currently on T Amlodipine 5 mg od.Mr TLT has been having intermittent chronic cough for the past 3 years. The cough is productive at times. The sputum produced is mucoid in disposition and about one tablespoonful in amount. There is no melody in the sputum. It is also not foul-smelling. Mr TLT then proceeded to have shortness of breath for the past one year. The dyspnoea is persistently present and described as requiring increased effort to breathe. It is worse on exertion and Mr TLT experinces reduced effort tolerance. He is now able to c tree branch one and a half flights of steps onwards becoming breathless(prenominal). He has not consulted any doctors for these symptoms prior to admission.Mr TLT then developed symptoms of upper respiratory tract infection much(prenominal) as rhinorrhea and sore throat one week prior to admission. He had fe ver of 38 degress celcius at that time which resolved with paracetamol. He also had a productive cough with mucoid sputum at this time. Mr TLT then developed increase shortness of breath 4 days prior to admission. The shortness of breath worsened over the 4 days and was associated with noisy breathing. He was breathless even at rest but was still able to speak in sentences. There was also an increase in cough as well as production of sputum. The sputum was mucoid and non purulent. He also did not notice any blueness around his lips or at his fingers.Systemic palingenesis There was no personnel casualty of appetite or loss of weight. He had mild mortise-and-tenon joint edema but no other signs of heart trouble such as orthopnoea or paroxysmal nocturnal dyspnoea.Past health check historyMr TLT has not had any hospital admissions prior to this. He was diagnosed with hypertension goal year as an incidental finding during a visit to the kilinik kesihatan for an upper respiratory tr act infection. He is currently taking tablet Amlodipine 5 mg once chance(a).Family historyMr TLT is the eldest of 5 siblings. There is a strong family history of hypertension in that his mother as well as cardinal other siblings are also hypertensive. There is no family history of asthma, diabetes or ischaemic heart ailment. loving historyMr TLT intentiond to work as a taxi driver but has stopped working full time 2 years ago. He still occasionally drives his taxi but spends more(prenominal) time at home with his family. He is a chronic smoker for the past 40 years and smokes about 20 sticks of cigarrettes a day.

He was able to speak in sentences but at that place was uptake of his accessory muscles. There was no club or cyanosis seen. There was also no peripheral oedema, pallor or jaundice.Vital signsPulse rate 72 beats per minute, regular with good volume. No bounding pulse.Respiratory rate 28 breaths per minute root pressure 129/73Temperature 37 degrees CelsiusSpO2 95% under nasal prong oxygen 3 litres per minute examen of the respiratory systemOn supervision of the hands, in that location was no peripheral cyanosis or flapping tremors seen. There was also no clubbing, muscle wasting or palmar erythema seen. There was presence of nicotine stains. The jugular venous pressure is mildly upgrade at 3.5 cm above the sternal angle. On palpation of the windpipe, the trachea is central but the cricosternal distance is 2 fingers which is reduced. The apex beat could not be palpated.On inspection of the chest, there is an increased anterior posterior diameter giving rise to a barr el regulate chest. The chest moves equally with respiration and there is habit of accessory mucles with intercostal, subcostal and suprasternal retraction. There are no chest wall deformities. On palpation, chest expansion is reduced on both sides. Tactile fremitus is equal on both sides. On percussion, there is hyperresonance over both lungs with loss of liver and cardiac dullness. On auscultation vesicular breathing is perceive. There is generalised expiratory rhonchi. There is also fine early inspiratory crepitations heard at the lower zones of both lungs.Examination of the cardiovascular systemThe apex beat could not be palpated. There were no parasternal heaves or thrills palpable. On auscultation, normal set-back and second heart sounds were heard. There was mild bilateral pitting oedema.Examination of the abdomenOn inspection, the abdomen is flat and moves with respiration. There was no guarding or tenderness. The liver and spleen were not palpable. There was no organomeg aly.Examination of the neurological system was normal.STUDENT NAME Tan Hai Liang ID NO M0409146NAME OF SUPERVISOR Prof Khin ROTATION Internal Medicine4) tentative AND DIFFERENTIAL DIAGNOSES WITH REASONINGProvisional diagnosisAcute exacerbation of newly diagnosed chronic hindering flight path distemper due to upper respiratory tract infection.Evidence forPatients with chronic obstructive airway ailment (COPD) unwashedly present with a persistent dyspnoea and reduced effort tolerance which was present in the history given by Mr TLT. He is also at increased risk of developing COPD due to exposure to associated risk factors such as tobacco smoke. He has been a chronic smoker for the past 40 years. There is also the presence of chronic cough occasionally associated with mucoid sputum which come on suggests COPD. Physical findings of a hyperinflated chest and vesicular breathing with generalised expiratory rhonchi also point to an obstructive airway affection.During this admission Mr TLT had increasing severity of shortness of breath even at rest. This was associated with a wheeze that was described as noisy breathing. Sudden worsening of symptoms suggest an episode of acute exacerbation. The history of upper respiratory tract infection symptoms suggest that it was the trigger for this episode of exacerbation.Differential diagnosis1) Congestive cardiac failure.Mr TLT may have developed congestive cardiac failure as a primary causa or as a complication of chronic lung disease. There is history of reduced effort tolerance. Patients with congestive cardiac failure may also present with a wheeze and sudden increase in dyspnoea. Physical examination of fine crepitations at both bases of the lungs may also indicate congestive cardiac failure. There is also evidence of mildly raised JVP as well as mild pittint ankle oedema.Evidence againstThere is no history of any cause of heart failure such as ischaemic heart disease or cardiac valve defect. Mr TLTs previous rec ords during inspection show well controlled blood pressure.Additional investigations need to be carried out in order to rule out this condition. A chest plain radiograph may be through in order to get wind for evidence of heart failure such as cardiomegaly. An ECG may be done to find for right atrial hypertrophy. An echocardiogram should also be make outed in order to assess the function of the ventricles.2) BronchiectasisPatients with bronchiectasis have a history of chronic cough as well as production of copious amounts of sputum. They may also have persistent shortness of breath, reduced effort tolerance and wheeze.Evidence againstThe sputum produced by Mr TLT is mucoid in nature and not purulent which is typical in bronchiectasis. It is also not copious and foul smelling in nature. On physical examination, coarse crepitations would be heard in bronchiectasis as opposed to the fine crepitations heard in Mr TLT. There is also no evidence of clubbing.Chest plain radiograph shou ld be done in order to look for thickened bronchial walls or cystic shadows.STUDENT NAME Tan Hai Liang ID NO M0409146NAME OF SUPERVISOR Prof Khin ROTATION Internal Medicine5) IDENTIFY AND PRIORITISE THE PROBLEMS1. huskiness of breath and reduced effort toleranceMr TLTs chief complaint is shortness of breath. This may be attributed to the increase in number of goblet cells and later on fibrosis of the bronchial walls causing airway obstruction seen in chronic obstructive airway disease. The shortness of breath may be partially relieved with the use of nebulization of ipratropium bromide, salbutamol and normal saline or with the use of metered dose inhalers. Chest physiotherapy may also be useful.Mr TLT also has had reduced effort tolerance and persistent dyspnoea for the past a year. As such he may require the use of ipratropium bromide in a metered dose inhaler upon discharge in order to feel less breathless due to the bronchodilator effect of the ipratropium bromide.2. Upper respi ratory tract infectionMr TLT may require antibiotics as he still has symptoms of upper respiratory tract infection such as sore throat. Furthermore patients who present with an acute exacerbation are at great risk of having a bacterial infection. This is because of the depressed immune state that the patient is in as a result of the acute illness as well as due to any steroids that would be given as part of the caution plan. The separateness of usage of antibiotics in chronic obstructive airway disease will be gain discussed below.3. Adequate inhaler techniqueMr TLT would need to be taught about the overcompensate technique to be apply when using metered dose inhalers. He would probably require daily use of ipratropium bromide metered dose inhalers to reduce his breathlessness. In the event that he is unable to learn proper technique, he may be encouraged to buy an aerochamber.4. Smoking periodMr TLT should be counseled on smoking expiration as it has been proven that smokin g period would alter the course of progression in COPD and is associated with lower all-cause mortality. He should be counseled on the various options of smoking cessation which will be discussed further below.STUDENT NAME Tan Hai Liang ID NO M0409146NAME OF SUPERVISOR Prof Khin ROTATION Internal Medicine6) PLAN OF INVESTIGATION, JUSTIFICATIONS FOR THE pickaxe OF TESTS OR PROCEDURES, AND INTERPRETATION OF RESULTS1) Full Blood Count acknowledgment In order to view the amount white numbering as well as the differential count to see if there is an infection which has caused this episode of exacerbation.

Provide supplemental oxygen via nasal prong 3L/min and maintain SpO2 above 90%. Arterial blood gas should be done in order to ensure adequate oxygenation without carbon dioxide retention of acidosis.2. refinement monitoring of vital signs and SpO2 hourly until the patients breathlessness improves. Nursing staff to inform if patient deteriorates such as increased respiratory rate or drop in oxygen saturation below 92%.3. Give nebulization of Ipratropium BromideSalbutamolNormal Saline in ratio of 221 all(prenominal) four hours until breathlessness decreases.4. Oral prednisolone 40mg once daily for 10 days5. Postural drainpipe and chest physiotherapy may be performed.6. Oral antibiotics such as T. Cefuroxime may be given.

His breathlessness improved after nebulization with ipratropium bromide, salbutamol and normal saline for one day. He no longer undeniable nebulization after one day. Mr TLT was also able to ambulate without feeling breathless. He was able to eat and to short sleep well without cosmos bothered by the dyspnoea. His vital signs were also normal and his respiratory rate improved to about 20 breaths per minute. There was still or so ronchi heard on auscultation but it was much reduced. He was afebri le during his stay.Mr TLT was discharged after 3 days of admission and educated on chronic obstructive airway disease. He was also counseled on the importance of smoking cessation. He was given an appointment with the medical outpatient department in one month time in order to review his symptoms after being given MDI ipratropium bromide. He was told to return to the hospital if he had similar episodes.STUDENT NAME Tan Hai Liang ID NO M0409146NAME OF SUPERVISOR Prof Khin ROTATION Internal Medicine9) DISCHARGE PLAN, COUNSELLING AND MOCK prescriptionDischarge Plan1.

Amlodipine 5mg once daily.He presented to Hospital Batu Pahat with shortness of breath for 4 days that was increasing in severity. A diagnosis of chronic obstructive airway disease was made. He was discharged uneventfully on the third day of admission with the following medication MDI Salbutamol 200g PRN, MDI Ipratropium Bromide 40g TDS and T. Amlodipine 5mg once daily.Mr Teo has been a chronic smoker for the past 40 years and smokes up to 20 sticks of cigarettes a day. We have counselled him about the benefits of smoking cessation while in the ward. He is currently considering it and would ilk to learn more about the various options of smoking cessation.Kindly assess the patients keenness for smoking cessation as well as provide him with additional information on the options available to quit smoking.Thank you.Sincerely____________(Tan Hai Liang)Medical Department Hospital Batu PahatSTUDENT NAME Tan Hai Liang ID NO M0409146NAME OF SUPERVISOR Prof Khin ROTATION Internal Medicine1 1) LEARNING ISSUES IN THE 8 IMU OUTCOMES1) Communication skillsWhat are the benefits of smoking cessation in COPD patients and how should counseling be done?Counseling for smoking cessation should play a significant role in the holistic management of a patient with chronic obstructive airway disease. This is because studies have shown that smoking cessation changes the clinical course of COPD by preserving lung function. One study of patients reviewed at 14.5 years after stopping smoking showed that smoking cessation interpellation showed 18% reduction in all-cause mortality compared with usual care without smoking cessation intervention. Patients who had stopped smoking had lower rates of death due of coronary heart disease , cerebrovascular disease, lung cancer, and other respiratory disease as compared with those assigned to usual care who continue to smoke. 1Fig. 4. Effect of smoking cessation on mortality cause at 14.5 years in the Lung Health Study.(A) Comparison of smoking c essation intervention with usual care. (B) Comparison according to smoking status.I therefore looked up for counseling methods for smoking cessation. The American College of Chest Physicians recommend that physicians should be the first line in introducing smoking cessation. 2 There are 5 As that a doctor should perform for a patient who is a smoker Ask about tobacco use at any visit Advise tobacco users to quit Assess the willingness to attempt quitting Assist the patient with methods for quitting Arrange for follow-up contact via phone or face to faceIf the patient is not yet willing to quit, there are 5 Rs which should be identified together by the patient and the doctor Relevance of quitting for the patient Risks of illness related to continued tobacco use Rewerds/benefits of smoking cessation Roadblocks for quitting, internal and external repeating of the motivation intervention at each encounterThere are two means of intervention in smoking cessation namely pharmacological a nd behavioural. The pharmacological means include nicotine replacement therapy or buproprion. Behavioural interventions include counseling programs that teach problem-solving skills and stick up groups. 3In conclusion, I learned that doctors have an primal role in actively encouraging patients who smoke to stop as there are many proven benefits of smoking cessation. The steps discussed above on techniques in the counseling of patients would be helpful to me in the future.2) Professionalism, ethics and personal developmentShould antibiotics be given for episodes of exacerbation of chronic obstructive airway disease?Mr TLT was not given antibiotics during this episode of exacerbation. Certain quarters support the use of prophylactic antibiotics in all exacerbations due to the knowledge that most exacerbations are caused by the common organisms of Streptococcus pneumoniae (S. pneumoniae), Haemophilus influenzae (H. influenzae), Pseudomonas aeruginosa (P. aeruginosa) and Moraxella cat arrhalis (M. catarrhalis).Sputum culture may not be useful as even in the clinical stable state, some patients have sputum positive for bacteria. As such a broad spectrum antibiotic is usually used to cover different bacteria. thus far, is this use of antibiotics justified in that do patients benefit from it or is the overjudicious use of antibiotics save promoting antibiotic resistant bacteria?Current Global initiative for chronic Lung Disease guidelines 4 recommend that antibiotics should be given ini) patients with exacerbations of COPD and the three cardinal symptoms of increaseddyspnoea, increased sputum volume and increased sputum purulence.ii) patients with exacerbation of COPD with two of the cardinal symptoms if increasedpurulence of sputum is one of the two symptomsiii) patients with severe exacerbations of COPD that requires robotic ventilationA meta-analysis by Ram et al 5 of 11 placebo controlled RCTs with 917 patients attempted to analyse the value of antibiotics in the management of acute COPD exacerbations. The results show that there is a decrease in short-term mortality, treatment failure and sputum purulence with antibiotic therapy compared to placebo. The authors concluded that antibiotics therapy is appropriate in exacerbations of COPD associated with increased cough and sputum purulence. They further install that antibiotics have the greatest effect for patients with severe exacerbations who are admitted to the hospital. They were unable to comment on exacerbations with non-purulent sputum, what antibiotics were the outflank to be used and also the duration of therapy due to the lack of RCTs done on these aspects.In conclusion, it was appropriate that Mr TLT was not given antibiotics as he did not have the cardinal signs as mentioned by the atomic number 79 guidelines and further supported by the systemic review.3) Self directed life long learningWhat are extrapulmonary manifestations of COPD and what are its therapeutic implication s?Chronic obstructive lung disease has long been known as a locate pulmonary disorder. However new evidence have shown that COPD may be a systemic disease that involves pathology in several extra-pulmonary systems.An article by Remels et al 6 summarized the extrapulmonary manifestations as well as its implications on the holistic management of chronic obstructive airway disease. The article showed that there is skeletal muscle dysfunction as well as systemic inflammation in chronic obstructive airway disease.There is loss of muscle ken associated with impaired protein metabolism. The loss of muscle mass which is called sarcopenia may progress to cachexia. Studies have also shown that there is increased apoptosis of muscle cells at the cellular level. Independent of the loss of muscle mass is the reduced muscle selection. This finding has been attributed to abnormalities in mitochondria or to hypoxia. These findings have significant implications on management of a COPD patient whi ch will be discussed below.Systemic inflammation is also seen in patients with COPD. This is evidenced by elevated levels of the proinflammatory cytokines such as tumor necrosis factor-alpha (TNF-a), interleukin-6, interleukin-8, and TNF-a receptors. The origin of the systemic inflammation is thought to be independent of the pulmonary manifestation of COPD. One postulation is the increase systemic inflammatory mediators such as neutrophils and lymphocytes in the circulation of patients with COPD. Another proposed mechanism is increased cytokine production due to chronic hypoxia.The therapeutic implications of these findings is that muscle cachexy should be prevented by resistance exercise as well as combined strength and endurance exercise. Current Malaysian guidelines on the management of COPD 7 recommend pulmonary resistance including lower and upper limb exercises as well as inspiratory muscle training. This concurs with a Cochrane metaanalysis by Lacasse et al 8 which strongly support respiratory at least four weeks of exercise training as part of the of management for patients with COPD. The authors found that there was clinically and statistically significant improvements in quality of life as measured by dyspnea, fatigue and emotional function.4. Critical thinking and researchWhat is the efficacy of systemic corticosteroids for acute exacerbations of chronic obstructive airway disese?The use of systemic oral or intravenous corticosteroids is recommended by GOLD guidelines in the management of acute exacerbations of chronic obstructive airway disease. However the patient, Mr TLT was not given any systemic corticosteroids. This could be because he merely had a mild exacerbation.I therefore looked up a Cochrane metaanalysis on the use of systemic corticosteroids for acute exacerbations of chronic obstructive airway disease 9. The authors reviewed randomized controlled trials comparing parenteral or oral corticosteroids with placebo for the treatment of ex acerbation of COPD. The primary outcomes measured were treatment failure (hospital readmission, return to emergency department), drop off and mortality.The authors reviewed 11 studies involving 1081 participants. The results show a statistically significant difference between placebo and use of corticosteoids. There was less treatment failure in patients given corticosteroids. Relapse within 30 days were also reduced. However there was no statistically significant reduction in mortality.As such the authors concluded that judicatory of oral or parenteral corticosteroids in the treatment of acute exacerbations of COPD reduces the likelihood of treatment failure. This is associated with early and go on improvement during treatment with corticosteroids in lung function, breathlessness and blood gases and with a shorter hospital stay. This in turn has a positve impact on the economic cost of treating exacerbations, with fewer follow-up visits and hospital admissions. The authors also found that although there is an increased incidence of corticosteroid side effects such as fluid retention, hypertension and adrenal gland suppression, the effects are unlikely to persist after treatment ceases.EVIDENCE BASED MEDICINE WORKSHEET FOR come off OF THERAPY STUDIESASKING QUESTIONPatient (P) Patients who present with stable COPDIntervention (I) Oral corticosteroidsComparison (C) PlaceboOutcome (O) do on health statusACCESSING EVIDENCE THE SEARCH PATHHow was the article identified The Cochrane Libraryhunt keywords corticosteroids, stable COPDCitation Walters JAE,Walters EH,Wood-Baker R.Oral corticosteroids for stable chronic obstructive pulmonary disease.
