Try to provide an epinephrine-pen (auto-injector of adrenaline) for emergency home administration. Reassure the parents that he will probably recover If he has had a thyroid operation, suspect recurrent spontaneously between 3-5yrs. Use a laryngoscope carefully to search the tonsils, the valleculae, and the back of the 30. Take the opportunity to have a look at the larynx, even though a foreign body here does cause different symptoms (29. Grasp it with Magill forceps, or pull it A patient with a foreign body in the pharynx, up with a Foley catheter (30. Most fish bones stick in accessible regions, usually the (2) Keep the head well down all the time, and the neck back of the tongue or tonsils. This is fortunate, because If the presentation is early with something in the this is the easiest place from which to remove them. Take radiographs, The patient may have almost no symptoms, or he may be especially a lateral view. The diagnosis is usually obvious, but a foreign body which is missed, can cause persistent dysphagia and loss of weight, so that you may suspect a carcinoma or oesophageal candidiasis. When it was explained that this was wrong, she repeated (correctly) that this was indeed the instrument that she had seen used at her rural hospital! If you do not have an oesophagoscope, you may be able to use a bronchoscope to remove coins from the oesophagus, or dilate a carcinoma before passing a Celestin tube (30-2E). The more protruding beak of a bronchoscope is, however, more likely to perforate the oesophagus. Many, but not all, foreign bodies are radio-opaque, but chicken and fish bones for example may be hard to see. This will be easier if you keep the handle of the instrument up, so that it slides over this (Its obviously no use performing an oesophagoscopy for muscle. B, keep the head on a pillow with the neck flexed and the something that is already in the stomach! Ultrasound may help deciding if an object is in the to pass the oesophagoscope as far as the deepest part of the thoracic oesophagus or bronchus. C, introduce the oesophagoscope obliquely and move it vertically, as it reaches the pharynx. You may be able to feel the foreign inflate the catheter balloon with enough water to occlude body with a probe, and remove it with a long clamp. The foreign body If laryngoscopy and simpler methods fail, pass the will come out with it, so you must grasp it quickly with oesophagoscope. As soon as you can see the foreign body clearly (usually a Make sure the neck is extended and the patient is coin, which will reflect the light and shine brightly as a head down. This manoeuvre is much When you have grasped it, bring it and the safer than using the oesophagoscope if you are oesophagoscope out together. The same position will allow you to pass the (1) The great danger is perforating the oesophagus: oesophagoscope into the deepest part of the thoracic (a) usually at the level of the cricopharyngeus which kyphosis. The most common reason for failure is keeps the entry closed, or insufficient flexion of the neck, and extension of the head. If you do not have an oesophagoscope, Beware of the lady with the elaborate towering hairstyle: you may be able to use a sigmoidoscope. Obviously you it will be safer to undo this, or just cut it off, must clean it and soak it in disinfectant before use! Have biopsy forceps and foreign body graspers If a foreign body is too large to remove whole, ready; check that these are long enough to pass through the as with an impacted denture, you may be able to break it oesophagoscope! If you fail to remove a foreign body and cannot dislodge Aim the oesophagoscope vertically downwards at the it distally (but take great care: this may perforate the uvula, keeping it at the back of the mouth against the oesophagus, especially if the foreign body has sharp edges palate. Angle it so as to pass the base of the tongue and is too large to fit inside the endoscope), you may be (aim at the foot of the pedestal of the table). Look for air in the neck, pleural cavity or mediastinum (1) Never advance the oesophagoscope blind or forcefully, (the earliest sign is a translucent crescent overlying the or you may perforate the oesophagus. If injury to the oesophagus is likely to be severe (you can sometimes tell early by the bleaching caused in If the above symptoms are delayed, there is the mouth and pharynx), do not hesitate to construct a fever and the chest radiograph is normal, feeding gastrostomy (13. Fashion a temporary oesophagostomy tube drainage in the neck (30-5) and a gastrostomy (13. The victim is usually a child under 5yrs, or an adolescent; occasionally it is the result of a suicide attempt. Do it with infinite care, otherwise you will perforate the oesophagus, and probably kill the patient. Oesophageal damage may also occur after excessive or misplaced injection of sclerosants for varices (13. If there is no severe complication immediately, A, pass a guidewire through the stricture (if the string is not already and the pain and dysphagia improve, the victim may think in place). Do not try to after ingestion of the corrosive and then weekly for inspect the whole length of the oesophagus with a rigid 3months: do not attempt >4mm dilation in one session. If subsequent dilations are easy, remove the Treat with cimetidine or ranitidine to lessen the risk of string. If the oesophagus is not dilated in the latent stage, the stricture will again get worse. Pass the oesophagoscope with care, using one hunger, thirst and weight loss, and even regurgitation due of small diameter first. Suck out residual fluid and advance to distal obstruction in the oesophagus or stomach. If you cannot pass a bougie by mouth, try the retrograde Try to introduce a well-lubricated bougie of size Ch10-12, method (30-2). If the reflux of so that you do not have to manipulate its passage each acid is severe and continuous, inflammation can lead to time. Strictures at the lower oesophagus are particularly This sort is, inevitably, at the lower third of the vulnerable because the oesophagus makes a slight curve oesophagus, where dilation is especially hazardous. If you ask the patient to point to <200/l is at high risk of developing fungal infestation the site where food sticks, it will usually correlate well with candidiasis. Regurgitation; this is common, except in the early chemotherapy, its appearance in the mouth is virtually stages; the patient may describe it as vomiting. This happens when the If candidiasis is limited to the lower oesophagus, lesion is in the upper or middle of the oesophagus. The endoscope easily gets blocked with thick candida, Palliate an inoperable carcinoma with a stent or tube so do these cases last on your list!
Malignant neoplasm composed of undifferentiated cells are said to be anaplastic cheap imitrex 25mg otc spasms medication, literally anaplasia means to form backward purchase 25mg imitrex with amex muscle relaxant high. Tumour giant cells and frequent loss of polarity of epithelial arrangements are encountered buy imitrex pills in toronto muscle relaxant 551. Thyroid, adrenal) so also, well differentiated squamous cell carcinoma and well differentiated hepatocellular carcinomas produce keratine and bile respectively. Rate of growth Most benign tumours grow slowly whereas; most malignant tumours grow rapidly sometimes, at erratic pace. Some benign tumours for example uterine leiomyoma increase in size during pregnancy due to probably steroidal effects (estrogen) and regress in menopause. In general, the growth rate of neoplasms correlate with their level of differentiation and thus, most malignant neoplasms grow more rapidly than do benign neoplasms. On occasions, cancers have been observed to decrease in size and even spontaneously disappear. Local invasion Nearly all benign neoplasms grow as cohesive expansile masses that remains localized to their site of origin and do not have the capacity to invade or metastasize to distant sites, as do malignant neoplasms. Thus, such encapsulations tend to contain the 192 benign neoplasms as a discrete, rapidly palpable and easily movable mass that can easily surgically enucleated. Generally, they are poorly demarcated from the surrounding normal tissue (and a well-defined cleavage plane is lacking). Several matrix-degrading enzymes including glycosidase may be associated with tumour invasion. Cartilage is probably the most resistant of all tissues to invasions and this is may be due to the biologic stability and slow turnover of cartilage. Malignant cell surface receptors bind to basement membrane components (ex laminin). Metastasis 193 Most carcinomas begin as localized growth confined to the epithelium in which they arise. As long as this early cancers do not penetrate the basement membrane on which the epithelium rests such tumours are called carcinoma in-situ. In those situations in which cancers arise from cell that are not confined by a basement membrane, such as connective tissue cells, lymphoid elements and hepatocytes, an in-situ stage is not defined. Metastasis It is defined as a transfer of malignant cells from one site to another not directly connected with it (as it is described in the above steps). The invasiveness of cancers permits them to penetrate in to the blood vessel, lymphatic and body cavities providing the opportunity for spread. Pathways of spread: Dissemination of malignant neoplasm may occur through one of the following pathways. Seeding of body cavities and surfaces (transcoelomic spread) This seeding may occur wherever a malignant neoplasm penetrates into a natural open field. Most often involved is the peritoneal cavity, but any other cavities such as pleural, pericardial, sub-arachnoid and joint spaces-may be affected. These carcinomas fill the peritoneal cavity with a 194 gelatinous soft, translucent neoplastic mass. Lymphatic spread Lymphatic route is the most common pathway for the initial dissemination of carcinomas The pattern of lymph node involvement follows the natural routes of drainage. Lymph nodes involvement in cancers is in direct proportion to the number of tumour cell reaching the nodes. The cut surface of this enlarged lymph node usually resembles that of the primary tumour in colour and consistency. The best examples of lymphatic spread of malignant neoplasm can be exemplified by breast carcinoma. Skip metastasis happen to occur because of venous lymphatic anastomoses or because inflammation or radiation has obliterated the lymphatic channels for example abdominal cancer (gastric cancer) may be initially signaled by supra clavicular (sentinel node). Conversely, the absence of tumour cells in reseated lymph nodes does not guarantee that there is no underlying cancer. Hematogenous spread Typical for all sarcomas and certain carcinomas- the spread appears to be selective with seed and soil phenomenon. Lung & liver are common sites of metastasis because they receive the systemic and venous out flow respectively. The site where tumour cell emboli lodge and produce secondary growth is influenced by Vascular (and lymphatic) drainage from the site of the primary tumour Interaction of tumour cells with organ specific receptors The microenvironment of the organ or site, example a tissue rich in protease inhibitors might be resistant to penetration by tumour cells. Cancer Epidemiology The only certain way to avoid cancer is not to be born, to live is to incur the risk. Over the years cancer incidence increased in males while it slightly decreased in females (due to largely screening Procedures-cervical, breast etc. In the studied populations the most common cancer in males is broncogenic carcinoma while breast carcinoma in females. Acute leukemias and neoplasms of the central nervous system accounts for about 60% of the deaths. Geographic factors (geographic pathology): Specific differences in incidence rates of cancers are seen worldwide. Inherited cancer syndromes (Autosomal dominant) with strong familial history include - Familial retinoblastomas usually bilateral, and a second cancer risk particularly osteogenic sarcoma. Oncosupressor gene is the basis for this carcinogenesis 196 - Familial adenomatous polyps of the colon. Endometrial hyperplasia - endometrial carcinoma Cervical dysplasia - cervical cancer Bronchial dysplasia - bronchogenic carcinoma Regenerative nodules - liver cancer Certain non-neoplastic disorders may predispose to cancers. Chronic atrophic gastritis - gastric cancer Solar keratosis of skin - skin cancer Chronic ulcerative colitis - colonic cancer Leukoplakia of the oral cavity, vulva and penis - squamous cell carcinoma Certain types of benign neoplasms Large cumulative experiences indicate that most benign neoplasms do not become malignant. Molecular Basis of Cancer (Carcinogenesis) Basic principles of carcinogenesis: The fundamental principles in carcinogenesis include 1) Non-lethal genetic damage lies at the heart of carcinogenesis. Such genetic damage (mutation) may be acquired by the action of environmental agents such as chemicals, radiation or viruses or it may be inherited in the germ line. They fall into the following three categories: a) Chemical carcinogenesis b) Radiation carcinogenesis c) Viral carcinogenesis A) Chemical carcinogenesis An enormous variety of chemicals may induce tumours and this was exemplified by Sir Percival Potts observation in the last century that astutely related the increased incidence of scrotal skin cancer in chimney sweeps to chronic exposure to soot. However, initiation alone is not sufficient for tumour formation and thus, promoters can induce tumours in initiated cells, but they are non-tumourogenic by themselves. Furthermore, tumours do not result when a promoting agent applied before, the initiating agent. Directly acting compound These are ultimate carcinogens and have one property in common: They are highly reactive electrophiles (have electron deficient atoms) that can react with nucleophilic (electron-rich) sites in the cell. Indirect acting compounds (or pro-carcinogens) Requires metabolic conversion in vivo to produce ultimate carcinogens capable of transforming cells. Miners for radioactive elements---lung cancer Therapeutic irradiations have been documented to be carcinogenic. Thyroid cancer may result from childhood & infancy irradiation (9%), and by the same taken radiation therapy for spondylitis may lead to a possible acute leukemia year later. The infection of B- cell is latent and the latently infected B-cell is immortalized.

Exclusion House flies enter homes by several means: doors which do not close properly or that do not have a good fit; windows without screens or with screens in ill repair purchase imitrex 25mg on line muscle relaxant walmart. Flies also enter buildings through tiny cracks around windows and doors; seal or caulk these areas buy generic imitrex 25 mg line spasms under xiphoid process. Sprays Space sprays and pheromone traps can be helpful tools in eliminating indoor blowflies cheap imitrex 25mg with visa muscle relaxant for stiff neck, but the elimination of their breeding sources is the only guaranteed way to eliminate them. Make certain that all possible sanitation measures have been implemented before relying on chemical sprays to eliminate flies. Space sprays can be used to knock down existing house fly infestations, but this is only a temporary fix. If breeding sites have not been eliminated or altered, house flies will continue to be a problem. Surface sprays can be used around windows and doors and should also be used on dumpsters. Any area where flies "rest" or enter in building can be treated with a good surface spray. However, do not spray areas that humans constantly come into contact with or on surfaces where food is prepared or served. If so, do not bait inside the container, but bait the area surrounding the receptacle. Common House Fly and Other Related Flies Biology The common house fly, is a pest all over the world. The adult has the fourth wing vein sharply angled and four length-wise dark stripes on the top of the thorax. Each adult female begins laying eggs a few days after hatching, laying a total of five to six batches of 75 to 100 small, white oval eggs. In warm weather these hatch in 12 to 24 hours into cream-colored larvae which burrow into the food material on which they hatched. When fully formed, the adult fly breaks open the end of the pupal case and emerges. The hardened larval skin which is left behind still exhibits most of the characteristics which are used in larval identification; thus determination can often be made on the basis of the skin alone. The method of over wintering is not well understood, but in some areas populations develop indoors throughout the winter. House fly eggs are laid in almost any warm moist material which will furnish suitable food for the growing larvae. Animal manure, human excrement, garbage, decaying vegetable material and ground contaminated with such organic mater are suitable materials. Although they are attracted to a wide variety of food materials, house flies have mouthparts which enable them to ingest only liquid materials. This liquefied food is then drawn up by the mouthparts and passed onto the digestive tract. During daylight hours house flies will rest on floors, walls and ceilings indoors. Outdoors they will rest on plants, on the ground, on fence wires, garbage cans and other similar surfaces. At night they will rest principally on ceilings, electric wires and dangling light cords indoors. In all situations they prefer corners and edges or thin objects such as wires and strings. Night resting places are usually near daytime sources of food and are usually 5 to 15 feet off the ground. Exclusion and Sanitation: - Sanitation is the first measure of defense, even though there are various traps and sprays that are used to kill flies, it is necessary to eliminate the source in order to eliminate them. Killing adult flies will reduce infestation, but elimination of breeding areas is necessary for good management. Trapping-Glue and Outside Window Fly Trap-allows you to use a trap to stick on the window, without using an insecticide. Advantage of fly trap is an excellent trap for the outside, with a unique attractant lure included. Electronic traps: Inside Use electronic fly traps are very efficient and functional: Properly fitting screen doors and windows are essential to exclude flies from homes and other areas where food is prepared. A combination of good sanitation and mechanical exclusion will produce the same effect and keep fly populations under control. Elimination of potential breeding sites will help in the general reduction of fly numbers. Pet faeces should be removed and fresh manure and other compost dug into garden beds. Routine emptying and cleaning of all garbage 145 receptacles will reduce breeding. People traveling to destinations that may include rural areas of Africa, Central and South America, should be aware of possible infection by the immature stages of several exotic flies. The three basic principles of house fly control are sanitation, exclusion and non-chemical measures. Sanitation will provide the best long-term control, followed by exclusion and non-chemical measures, which provide shorter-term management. Exclusion: Flies can be kept outside of homes by the use of window and door screens. Check for openings around water or gas pipes or electrical conduits that feed into the building. Ventilation holes should be screened, as they can serve as entryways for flies as well. Phaenica cuprina Genus 5: Phormia Species - Phormia regina - Black blow fly. General Features of Calliphoridae: Blue or Blow flies All calliphoridae have world wide distribution. Their breeding place is on waste, decaying animal matter, and some lay their egg on flesh and make human food unfit. The female cochliomia hominivorax lay their eggs on wound and result in myiasis particularly on sheep, goat and cattle. Calliphora species also lay their egg on wound and the developing 147 maggot damage the neighbouring tissues example Lucilia illustries. Public Health Importance: Generally calliphorids are responsible to cause myiasis. Prevention and Control of Calliphoridae: Basic sanitation:- By proper disposal of both human and animal wastes, it is possible to control the immature stages of these flies. From the non- residual insecticide the pyrethrins are the best to kill adult flies while flying or resting.
