Incidence of nodal recurrence in 131I treated patients is lower than the reported range of 24-34% in patients not given 131I [9 gastritis symptoms home remedies buy 20 mg esomeprazole otc. Pulmonary metastases There is a greater consensus regarding the need to give 131I for lung metastases in comparison with that of treating remnant thyroid tissue gastritis diet recommendations esomeprazole 20mg without a prescription. It is known that 131I concentration in clinically stable lung metastases may persist for many years [9. Although 131I treatment for ablating residual tissue as well as pulmonary metastases has been found to be safe, several treatments over a number of years can rarely result in radiationinduced fibrosis leading to pulmonary insufficiency. Retrospectively, it appears that patients who have radiographically stable pulmonary metastases or minimal 131I concentration may be monitored conservatively with thyroglobulin (Tg) measurement, chest X ray and pulmonary function tests without further 131I therapy, albeit in children X ray is not a good modality to detect early disease in lungs. Tumour response to radioiodine therapy and possible adverse effect Overall, the radioiodine therapy in children is effective and gives long term disease-free survival. However, none of the independent co-variates like sex, histopathology, 131I uptake, administered and absorbed dose appears to have any influence over the dependent variable (ablation) [9. It seems that there is one elusive factor which affects radioiodine ablation of thyroid tissue. This biological variable is unknown, undefined and unpredictable and currently unmeasurable. One of the possible adverse effects of treatment with 131I, especially in children, is its effect on the gonads. For further details, please refer to the Chapter "Long term Follow-up Strategies". External radiotherapy External radiation plays a minor role in the management of childhood thyroid cancer. It is useful in special situations where either the primary tumour is inoperable or there is an extensive invasive disease with soft tissue, tracheal or oesophageal infiltration. The outcome of the treatment is usually unsatisfactory and the post-therapy complications are frequent and severe. Thereafter, the patients can be followed with yearly clinical examination, chest X ray and Tg determination. Mortality the overall mortality rate reported in the literature varies from 0-18%. The reported respective 5-year, 10-year, 15-year, and 20-year survival is 90-95% [9. Despite the aggressive nature of thyroid carcinoma in children, the outcome and long term survival is very good. Although rare, occasional mortalities do occur especially in children who are less than 10 years old at the time of diagnosis. Prognostic factors the host and tumour factors are predictor of survival in almost all cancers. None of the known variables like age, sex, histology, type of surgery, radioiodine therapy and nodal status influences survival. This is because very few large series have been published with long term follow-up. In most of the published report the number of children is too small, and the upper age cut-off varies from 12-year to 25-years that does not permit robust statistical analysis. However, to determine death rate, the duration of follow-up should be longer than 5 years in the majority of patients. On the other hand, it is well known that the vast majority of recurrences occur in the first 5 years after the primary treatment. Therefore the importance of prognostic factors is calculated in relation to disease-free survival. There is disagreement in the literature on the relation between tumour histopathology and disease free survival. In this series, there was no correlation between tumour histopathology and disease-free survival, although the patients with follicular cancer were quite numerous. This is probably due to the moderate iodine deficiency which was observed in Northern India till mid eighties [9. Recently, more and more authors have claimed that local metastases adversely influence disease-free survival [9.
It usually is advisable to adjust both electrolyte and acid-base imbalances slowly chronic gastritis gas purchase esomeprazole online from canada, since too rapid correction often leads to overshoot or intracellular-extracellular imbalances and worsens the clinical situation gastritis wine buy esomeprazole 20mg. Many emergency departments can provide a rapid assessment of toxic drugs (Table 76). Therefore, no stuporous or comatose patient suspected of having ingested sedative drugs should ever be left alone. This is particularly true in the minutes immediately following the initial examination; the stimulation delivered by the examining physician may arouse the patient to a state in which he or she appears relatively alert or his or her respiratory function appears normal, only to lapse into coma with depressed breathing when external stimulation ceases. The management of specific drug poisonings is beyond the scope of this chapter,88,94 but certain general principles apply to all patients suspected of having ingested sedative drugs. Both respiratory and cardiovascular failure may occur with massive sedative drug overdose. Anticipation and early treatment of these complications often smooth the clinical course. Insert an endotracheal tube in any stuporous or comatose patient suspected of drug overdose and be certain that an apparatus for respiratory support is available in case of acute respiratory failure. The placement of a central venous line allows one to maintain an adequate blood volume without overloading the patient. Give generous amounts of fluid to maintain blood volume and blood pressure, but avoid overhydrating oliguric patients. Place a pulse oximeter on the finger, but also measure arterial blood gases; a difference between the two (oxygen saturation gap) may indicate poisoning. Carbon monoxide, methemoglobin, cyanide, and hydrogen sulfide cause an increased oxygen saturation gap. Once the vital signs have been stabilized, one should attempt to remove, neutralize, or reverse the effects of the drug. Attempts to remove poi- son from the gastrointestinal tract and thus prevent absorption have included inducing vomiting with syrup of ipecac,95 gastric lavage,96 cathartics,97 activated charcoal ingestion,98 and whole bowel irrigation. Multiple doses of charcoal administered at an initial dose of 50 to 100 g, and then at a rate of not less than 12. In addition to eliminating drugs from the small bowel, the agents may interrupt the enteroenteric and, in some cases, the enterohepatic circulation of drugs. Doses above 5 g in adults may cause acute hepatic injury, especially if combined with other hepatotoxins such as ethanol, and when acetaminophen overdose is suspected, the patient should be treated with N-acetylcysteine as well. Once one has considered the possibilityofpsychogenicunresponsivenessandperformed the appropriate neurologic examination, little difficulty arises in making the definitive diagnosis. If the patient meets the clinical criteria for psychogenic unresponsiveness, no further laboratory tests are required. In emergency evaluation of the unresponsive patient, the Amytal interview may establish the diagnosis and ``wake the patient up,' so that one may begin more definitive treatment. However, it also breaks down a major psychologic defense, and should only be done in conjunction with definitive psychiatric treatment. Hence, it is necessary to secure emergency psychiatric consultation, and often the patient must be admitted to the psychiatric service. If there is any suspicion of a mass lesion, immediate imaging is mandatory despite the absence of focal signs. Conversely, the presence of hemiplegia or other focal signs does not rule out metabolic disease, especially hypoglycemia. At all times during the diagnostic evaluation and treatment of a patient who is stuporous or comatose, the physician must ask him- or herself whether the diagnosis could possibly be wrong and whether he or she needs to seek consultation or undertake other diagnostic or therapeutic measures. Fortunately, with constant attention to the changing state of consciousness and a willingness to reconsider the situation minute by minute, few mistakes should be made. The locked-in syndrome: what is it like to be conscious but paralyzed and voiceless? Intubation without premedication may worsen outcome for unconsciousness patients with intracranial hemorrhage.

Classifications Joints are classified by two methods · · By function-degree of movement By structure presence of cavity. According to functional classification joints may be immovable (synartherosis), slightly movable (amphiartherosis) and freely movable (diarthrosis). According to structure joints can be classified in to , fibrous, cartilaginous & synovial. The main function of the skeletal system is: a) Protection b) Storage of minerals c) Support d) Producing motion e) All of the above 2. The two type of ridged connective tissue found in the human skeleton are: a) Spongy & compact bone b) Bone & cartilage c) Periosteum & endosteum d) Metaphysis & Diaphysis e) Cancellous & bone plate 3. The major bone at the posterior aspect of the base of the skull is: a) Sphenoid b) Occiputal c) Temporal d) Lacrimal e) Zygomatic 105 Human Anatomy and Physiology 4. Describe the structure of a muscle Describe the connective tissue components of skeletal muscles Briefly describe how muscles contract List the substances needed in muscle contraction and describe the function of each Differentiate between isotonic and isometric contractions Define the following terms: origin, insertion, synergist, antagonist, and prime mover Define the different bases employed in naming skeletal muscles Identify the principal skeletal muscle in different regions of the body by name, action, and innervations. The muscular system, however, refers to the skeletal muscle system: the skeletal muscle tissue and connective tissues that makeup individual muscle organs, such as the biceps brachii muscle. Cardiac muscle tissue is located in the heart and is therefore considered part of the cardiovascular system. Smooth muscle tissue of the intestines is part of the digestive system, whereas smooth muscle tissue of the urinary bladder is part of the urinary system and so on. We will see how skeletal system 108 Human Anatomy and Physiology produce movement and we will describe the principal skeletal muscles of the human body; their action and innervation. Functions of muscle tissue Through sustained contraction or alternating contraction and relaxation, muscle tissue has three key functions: producing motion, providing stabilization, and generating heat. Motion: Motion is obvious in movements such as walking and running, and in localized movements, such as grasping a pencil or nodding the head. Stabilizing body positions and regulating the volume of cavities in the body: Besides producing movements, skeletal muscle contractions maintain the body in stable positions, such as standing or sitting. Postural muscles display sustained contractions when a person is awake, for example, partially contracted neck muscles hold the head upright. In addition, the volumes of the body cavities are regulated through the contractions of skeletal muscles. For example muscles of respiration regulate the volume of the thoracic cavity during the process of breathing. These movements rely on the integrated functioning of bones, 109 Human Anatomy and Physiology Much of the heat released by muscle is used to maintain normal body temperature. Physiologic Characteristics of muscle tissue Muscle tissue has four principal characteristics that enable it to carry out its functions and thus contribute to homeostasis. Excitability (irritability), a property of both muscle and nerve cells (neurons), is the ability to respond to certain stimuli by producing electrical signal called action potentials (impulses). For example, the stimuli that trigger action potentials are chemicals-neurotransmitters, released by neurons, hormones distributed by the blood. Contractility is the ability of muscle tissue to shorten and thicken (contract), thus generating force to do work. Extensibility means that the muscle can be extended (stretched) without damaging the tissue. While one is contracting, the other not only relaxed but also usually is being stretched. Elasticity means that muscle tissue tends to return to its original shape after contraction or extension. Connective Tissue Component A skeletal muscle is an organ composed mainly of striated muscle cells and connective tissue.
These projects under track D are innovative and represent a great opportunity for individuals interested in this type of study symptoms of gastritis flare up purchase esomeprazole 20mg with amex. Again it is expected that a written report gastritis sweating buy esomeprazole 20mg amex, suitable for submission to refereed journal will be completed by the end of the third year. The following guidelines must be followed to ensure the safe and appropriate administration of contrast media, minimizing the potential harmful effects, and to ensure the appropriate and safe use of power injection equipment. Power Injector - A medical device used for the intravenous or intra-arterial injection of contrast media at a pre-set dose and at a predetermined flow rate and pressure setting. Pediatric Patients- For the purpose of this policy, pediatric patients those less than 18 years of age. The radiologist, based on protocols, determines which procedures require the use of contrast, which types of contrast to use, the contrast dose, and route. In addition, the radiologist will also determine if a power injector will be used. The power injector competencies will be done annually as a part of the annual performance evaluation. The radiologist will establish written procedure protocols that describe the appropriate use of power injectors. The Radiologist will then order which protocol the technologist will follow for each power injection procedure. The inpatient medical record is utilized to obtain information pertinent to contrast administration. Items reviewed include pertinent blood and urine tests, documented medical history, B. If the patient is responsive, the patient will be questioned about previous x-ray procedures involving use of contrast to gather information about any previous contrast reactions. The technologist or the nurse will interview the patient and review the appropriate lab tests prior to the administration of contrast if indicated by the responses on the contrast medium questionnaire. If there is a life threatening or critical indication the ordering physician may override the requirement to obtain a Creatnine prior to contrast administration. The radiology faculty, fellow, or resident must be notified before administering contrast in these situations: a. They may require a non-contrast study, a different exam, and/or preexam hydration (refer to the Iodinated Contrast/Hydration Protocol). The radiologist will be notified if the patient has had a previous reaction to contrast administration. The patient with a history of a contrast reaction will be interviewed for additional details about the previous contrast reaction, to include the following: a. Infants and young children are unable to verbalize discomfort or symptoms of contrast reaction; therefore, pediatric patients will be observed closely during all contrast injection procedures. For pediatric patients dose is 2 mL/kg of non-ionic contrast, up to a maximum of 100 mL unless otherwise ordered by the Radiologist. Gadolinium dosing will be calculated using millimoles per kilogram of patient body weight except for specified protocols that use a set dose. Oral contrast agents may be ordered alone or in conjunction with intravascular contrast. The sending nursing unit will administer the contrast to all inpatients with an order for oral contrast. The contrast is to be mixed according to instructions for a 4% dilution of iodine. The need for rectal contrast will be determined by the radiologist administered in the Radiology department. All intravascular lines accessed for contrast administration will be cleaned prior to access in accordance with the most current Infection Control policy. If not drawn and used immediately, all syringes containing contrast should be labeled with name of the contrast, the concentration, date, amount if not apparent from the container, time, expiration time when expiration occurs in < 24 hours, and initialed by the person preparing or opening the syringe. The technologist may use an existing saline lock for contrast administration after verifying patency.
