Bronchoscopy and Bronchoalveolar Lavage (BAL) .

What is Bronchoscopy and Bronchoalveolar Lavage (BAL)?

Bronchoscopy is a procedure in which a doctor uses a flexible tube with a camera at the end to look inside the lungs. This tube is inserted through the nose or mouth and passed to the airways in the lungs. Bronchoalveolar lavage (BAL) is a type of bronchoscopy in which a sample of the fluid (or lavage) is collected from the walls of the air passages.

Preparation For Bronchoscopy and BAL

Your doctor may require you to fast before the procedure. You may also be asked to decrease medication or stop taking certain medications. Depending on the preparation, you may need to take laxatives or special substances that clean the air passages. Your doctor will explain any preparation required for the procedure.

Procedure for Bronchoscopy and BAL

Before the procedure, you will be given medication to help you relax. Once you are relaxed, the doctor will insert a small flexible tube with a camera at the end through your nose or mouth into the airways of the lungs. The doctor will then move the tube to different parts of the airways to view the condition of the tissue in the lungs. During a BAL, the doctor will collect a sample of the fluid (or lavage) from the walls of the air passages. This fluid is then sent to a laboratory to be analyzed. The analysis of this fluid helps to identify any problems with the airway tissue.

Types of Bronchoscopy and BAL

Bronchoscopies and BALs are usually done in the hospital or clinic under general anesthesia. However, some bronchoscopies can be done with a local anesthetic. In rare cases, an awake bronchoscopy may be done without the use of anesthesia.

Risks of Bronchoscopy and BAL

Like any procedure, there are some risks associated with bronchoscopy and BAL. These risks include infection, bleeding, and allergic reactions to the medications used. Some other rare risks include damage to the airways and tissue of the lungs, lung collapse, and breathing difficulties.

Why is Bronchoscopy and BAL Needed?

Bronchoscopy and BAL are usually done to diagnose and monitor lung problems such as infections, tumors, or other abnormalities. It can also be used to remove fluids from the lungs, such as mucus. The procedure is also used to treat certain conditions, such as airway opening.

When is Bronchoscopy and BAL Needed?

Bronchoscopy and BAL may be recommended if you have symptoms of lung problems such as wheezing, shortness of breath, or coughing up blood. The procedure may also be recommended if you have a chest X-ray that suggests an abnormality. Your doctor may suggest the procedure to treat certain lung conditions.

Of all the amusements which can possible be imagined for a hard-working man, after his day’s toil, there is nothing like reading an entertaining book. It calls for no bodily exertion of which he has had enough. It relieves his home of its dullness. It transports him to lovelier and more interesting scenes; and while he enjoys these, he may forget the evils of the present moment. Nay, it accompanies him to his day’s work, and if the book he has been reading be anything above the very idlest and lightest, it gives him something to think about during the drudgery of his everyday occupation. If I were to pray for a taste which should stand me in good stead under every variety of circumstances and be a source of happiness and cheerfulness through life, it would be a taste for reading. Give a man this taste and the means of gratifying it, and you will never fail to make him happy, unless indeed you put into his hands the most perverse selection of books. You place him with the best society in every period of history, with the wisest, the wittiest, the tenders, the bravest and the purest characters which have adorned humanity. You make him a citizen of all nations, a contemporary of all ages. (Translate to Bangla)

Read the following passage carefully and answer the questions given below.The Italian banking system became the model for those North European nations that would achieve the greatest commercial success in the coming centuries, notably the Dutch, the English, and the Swedes. It was in Amsterdam, London and Stockholm that the next decisive wave of financial or innovation occurred, as the forerunners of modern central banks made their first appearance. The seventeenth century saw the foundation of three distinctly novel institutions that, in their differen in ways, were intended to serve a public as well as a private financial function. The Amsterdam Exchange Bank, i.e. the Wisselbank, was set up in 1609 to resolve the practical problems created for merchants by the circulation of multiple currencies in the United Provinces, where there were no fewer than fourteen different mints and copious quantities of foreign coins. By allowing merchants to set up accounts denominated in a standardized currency, the Exchange Bank pioneered the system of cheques and direct debits or transfers that we take for granted today. This allowed more and more commercial transactions to take place without the need for the sums involved to materialize in actual coins. Financial historians disagree as to how far the growth of banking after the seventeenth century can be credited with the acceleration of economic growth that began in Britain in the late eighteenth 20 5 century and then spread to Western Europe, North America and Australasia. But banks played a more important role in continental European industrialization than they did in England's.a) Where did the precursors of modern central banks make their first appearance? b) What practical problem was the Wisselbank required to resolve in its initial days?c) How did the Amsterdam Exchange Bank respond to the demand of the age? d) What are the points of disagreement among the financial historians with respect to growth of banking vis-a-vis growth of economy? e) Choose a suitable title for above composition.

Write a precis of the following paragraph and provide a title:The stated intention of most regulators is to maintain stability within the financial services sector, thereby protecting the consumers whom banks serve and the 'real' economy which the industry supports. Every shock to the financial system must result in casualties. Left to itself, natural selection should work fast to eliminate the weakest institution in the market, which typically are gobbled up by the successful. But most crises also usher in new rules and regulations, as legislators and regulators rush to stabilize the financial system and to protect consumers who are also voters. The critical point is that the possibility of extinction cannot and should not be removed by excessively precautionary rules. As Joseph Schumpeter wrote more than seventy years ago, 'This economic system cannot do without the ultima ratio of the complete destruction of those existences which are irretrievably associated with the hopelessly unadapted.' This meant, in his view, nothing less than the disappearance of 'those firms which are unfit to live'. It remains to be seen whether the extraordinary measures taken by Western governments since September 2008 will have the desired effect of preventing complete breakdown of the financial system or whether they will in fact end up impeding the process of financial evolution.
