The cells are then fixed in formalin followed by paraffin embedding just like a tissue sample medicine hat lodge 500 mg hydrea buy fast delivery. If these cell blocks contain a sufficient number of cells treatment as prevention cheap hydrea 500 mg mastercard, they serve as a very helpful reserve for further examinations such as immunohistochemical or sometimes molecular genetic tests ure 1 medications kidney damage quality hydrea 500 mg. Different methods of labeling, such as bar coding, can be used for coding the samples. The process of tissue examination by a pathologist begins by naked eye exam ination. A lot of information can be obtained after a careful macroscopic tissue examination or grossing. For small biopsy samples, these pieces of information are usually limited to the dimensions, as well as the number, color, and amount of the 1. It provides basic information regarding the adequacy of the specimen for further evaluations. In the case of some specific types of specimens, it is the duty of the pathologist to examine the small specimens by a hand lens or by a low-power microscope before subjecting it to complete formalin fixation and ordinary tissue processing. By low-power microscopic examination, the pathologist can tell the clinician whether he or she was successful in obtaining an adequate amount of renal tissue. On the other hand, the patholo gist may need to divide the sample appropriately into three portions. Each portion is then handled differently for different methods of examination, that is, fresh tissue for immunofluorescent examination, fixation in glutaraldehyde for electron microscopy, and fixation in buffered formalin for conventional tissue microscopy and specific chemical staining. The last option represents the standard procedure that is applicable in all cases. The most important role of grossing is in the evaluation of large resection samples. It is evident that microscopic evaluation of a whole resection sample, for example, the complete removal of an organ or extremity, is neither possible nor necessary. There are specific guidelines from which a pathologist can obtain information on how a resection specimen should be sampled and examined for microscopy. In this situation, the clinicians might want to know the extent of the tumor and the completeness of its removal. The macroscopic examination defines the exact location, size, shape, and configuration of the tumor, the depth of local invasion (in tumors of luminal structures such as intestinal tract), the relationship with adjacent normal tissue, and the distance from surgical resection margins. It is also necessary to look for lymph nodes to examine them for possible metastatic foci. According to the guidelines, a pathologist takes small tissue fragments from the tumor, resection margins, and lymph nodes, which should not be less than a minimum recommended number. In some types of specimens, for example, radical prostatectomy specimens, it is recommended to completely embed the specimen in thin sections. To maintain the orientation during the microscopic examination, it is sometimes necessary to paint the specific areas such as resection margins by the different colors of specific dyes. On this cassette, the code number of the specimen and if necessary the specific code of the area of sampling are written or typed. Tissue processing is a vital step for preparing the tissue slices for microscopic examinations. The processing of tissue is enhanced and accelerated in new-generation tissue processors by the application of microwave energy or vacuum. Now the tissue is ready to be cut to obtain thin slices for microscopic examinations. Using specific sharp blades and a precisely designed device, it is possible to cut the paraffin blocks into very thin sections (preferably 3–5 μm in thickness). The sections are placed on a glass slide, 8 1 Clinical Pathology stained, and finally cover by a cover slip. Then he or she makes a list of differential diagnoses and tries to reduce the size of this table by the application of specific laboratory tests. By careful examination of the microscopic changes on a slide, a pathologist tries to gather specific morphologic signs and symptoms (in this situation the key morphologic findings) in order to have a list of differential diagnoses.

Radiographic stud ies in cases of pituitary adenoma usually show enlargement of the bony structure in the skull (sella turcica) that contains the pituitary. Hypofunction of the pituitary, such as is caused by tumor or interruption of blood supply to the gland, may involve a single hormone but usually affects all functions and is referred to as panhypopituitarism. The widespread effects of this condition include dwarfism (from lack of growth hormone), lack of sexual devel opment and sexual function, fatigue, and weakness. Symptoms are polyuria (elimination of large amounts of urine) and polydipsia (excessive thirst). Diabetes insipidus should not be confused with diabetes mellitus, a disorder of glucose metabolism described below. The two diseases share the symptoms of polyuria and polydipsia but have entirely different causes. Diabetes mellitus is the more common disorder, and when the term diabetes is used alone, it generally refers to diabetes mellitus. The word diabetes is from the Greek meaning “siphon,” referring to the large urinary output in both forms of diabetes. Thyroid Because thyroid hormone affects the growth and function of many tissues, a deficiency of this hormone in infancy causes physical and mental retardation as well as other symptoms that together constitute congeni tal hypothyroidism, formerly called cretinism. In the adult, thyroid deficiency causes myxedema, in which there is weight gain, lethargy, rough, dry skin, and facial swelling. If not diagnosed at birth, hypothyroidism will lead to mental retardation within 6 months. The most common form of hyperthyroidism is Graves disease, also called diffuse toxic goiter. This is an autoimmune disorder in which antibodies stimulate an increased production of thyroid hormone. There is weight loss, irritability, hand tremor, and rapid heart rate (tachycardia). A most distinctive sign is a bulging of the eyeballs, termed exophthalmos, caused by swelling of the tissues behind the eyes. Treat ment for Graves disease may include antithyroid drugs, surgical removal of all or part of the thyroid, or radia tion delivered in the form of radioactive iodine. A young woman with hyperthyroidism presented with a mass in the neck and exophthalmos. With the addition of iodine to salt and other commercial foods, this form of goiter has become a thing of the past. Thyroid scans after the administration of radioactive iodine are also used to study the activity of this gland. Parathyroids Overactivity of the parathyroid glands, usually from a tumor, causes a high level of calcium in the blood. Be cause this calcium is obtained from the bones, there is also degeneration of the skeleton and bone pain. A common side effect is the development of kidney stones from the high levels of circulating calcium. Damage to the parathyroids or their surgical removal, as during thyroid surgery, results in a decrease in blood calcium levels. This causes numbness and tingling in the arms and legs and around the mouth (perio ral), as well as tetany (muscle spasms). Adrenals Hypofunction of the adrenal cortex, or Addison disease, is usually caused by autoimmune destruction of the gland. The lack of aldosterone results in water loss, low blood pressure, and electrolyte imbalance. This last symptom is caused by release of a hormone from the pituitary that stimulates the pig ment cells (melanocytes) in the skin. Patients have a moon-shaped face, obesity localized in the torso, weakness, excess hair growth (hirsutism), and fluid retention.

It is a sort of formal training which enables one to understand the new developments in one’s field in a better way medicine daughter lyrics hydrea 500 mg buy with mastercard. Research Methods versus Methodology It seems appropriate at this juncture to explain the difference between research methods and research methodology medicine 19th century 500 mg hydrea buy visa. Research methods may be understood as all those methods/techniques that are used for conduction of research medicine urinary tract infection buy discount hydrea on-line. Research methods or techniques*, thus, refer to the methods the researchers *At times, a distinction is also made between research techniques and research methods. Research techniques refer to the behaviour and instruments we use in performing research operations such as making observations, recording data, techniques of processing data and the like. Research methods refer to the behaviour and instruments used in selecting and constructing research technique. For instance, the difference between methods and techniques of data collection can better be understood from the details given in the following chart— Type Methods Techniques 1. Library (i) Analysis of historical Recording of notes, Content analysis, Tape and Film listening and Research records analysis. Field (i) Non-participant direct Observational behavioural scales, use of score cards, etc. Research observation (ii) Participant observation Interactional recording, possible use of tape recorders, photo graphic techniques. Laboratory Small group study of random Use of audio-visual recording devices, use of observers, etc. Research behaviour, play and role analysis From what has been stated above, we can say that methods are more general. However, in practice, the two terms are taken as interchangeable and when we talk of research methods we do, by implication, include research techniques within their compass. In other words, all those methods which are used by the researcher during the course of studying his research problem are termed as research methods. Since the object of research, particularly the applied research, it to arrive at a solution for a given problem, the available data and the unknown aspects of the problem have to be related to each other to make a solution possible. Keeping this in view, research methods can be put into the following three groups: 1. In the first group we include those methods which are concerned with the collection of data. These methods will be used where the data already available are not sufficient to arrive at the required solution; 2. The second group consists of those statistical techniques which are used for establishing relationships between the data and the unknowns; 3. The third group consists of those methods which are used to evaluate the accuracy of the results obtained. Research methods falling in the above stated last two groups are generally taken as the analytical tools of research. It may be understood as a science of studying how research is done scientifically. In it we study the various steps that are generally adopted by a researcher in studying his research problem along with the logic behind them. It is necessary for the researcher to know not only the research methods/techniques but also the methodology. Researchers not only need to know how to develop certain indices or tests, how to calculate the mean, the mode, the median or the standard deviation or chi-square, how to apply particular research techniques, but they also need to know which of these methods or techniques, are relevant and which are not, and what would they mean and indicate and why. Researchers also need to understand the assumptions underlying various techniques and they need to know the criteria by which they can decide that certain techniques and procedures will be applicable to certain problems and others will not. All this means that it is necessary for the researcher to design his methodology for his problem as the same may differ from problem to problem. For example, an architect, who designs a building, has to consciously evaluate the basis of his decisions, i. Similarly, in research the scientist has to expose the research decisions to evaluation before they are implemented. He has to specify very clearly and precisely what decisions he selects and why he selects them so that they can be evaluated by others also. From what has been stated above, we can say that research methodology has many dimensions and research methods do constitute a part of the research methodology. Thus, when we talk of research methodology we not only talk of the research methods but also consider the logic behind the methods we use in the context of our research study and explain why we are using a particular method or technique and why we are not using others so that research results are capable of being evaluated either by the researcher himself or by others.

Children with nutritional neglect present late with failure to thrive, poor hygiene, delayed immunisations, delayed speech, mental and social development. Most abused children are shy, have expressionless faces and avoid eye−to−eye contact. Vitamin A is important in: • Epithelial membrane integrity • Night vision • Immunity • Growth • Reproduction • Maintenance of life Source: • Animal products eg. Consequences of deficiency: Reduced immunity, keratinizing metaplasia of epithelial membranes, xerophthalmia, night blindness, keratomalacia and blindness. Vitamin A supplementation has been shown to result in 23−34% reduction of all childhood mortality (6−59 months), 50% reduction in measles mortality and 33% reduction in diarrhoeal disease mortality. Treatment for xerophthalmia Give Vitamin A on day 1, 2 and a third dose between 1−4 weeks after 2nd dose. Management • Bi−weekly attendance at the clinic • Treat any intercurrent problem e. Admit • For further assessment if no change after 3 months • If child develops moderate to severe malnutrition. Increase from 100 to 200 ml/kg/24 hrs as tolerated 197 • Frequent spaced feedings throughout 24 hrs are essential to prevent hypoglycaemia • Multivitamin syrup 2. With advancement in modern neonatology the technical definition denotes termination of pregnancy to a foetus weighing less than 500 gm. The cervical os is patulous, uterine cavity is empty and the uterus is well contracted. Signs and symptoms of pregnancy previously experienced are minimal or absent and there is no increase in abdominal girth. Illegal induced abortion by mainly, unqualified medical personnel is associated with incompleteness, sepsis, genital injuries and death. In the threatened stage, before the cervix opens, the diagnosis of hydatidiform mole is suspected if bleeding does not settle within a week of bed rest. Admit 199 • If more bleeding and signs of progression to incomplete abortion occur. Patient Education • Return to hospital if features of progression to incomplete abortion intensify e. Patient Education • If further pregnancy is desired, investigate further as under habitual abortion • If further pregnancy is not desired, discuss and offer appropriate contraception.

The consent form itself should not contain any new or detailed information treatment stye buy generic hydrea online, but simply state that the informant (study participant) consents to taking part in the study medications j tube discount hydrea express, as described in the information medicine 5658 hydrea 500 mg order with mastercard. In accordance with international 54 regulations, clinical drug trial consents must also include the name and signature of the person who has provided information to the study participant. The information letter and consent form in clinical drug trials must be dated and have a version number. Bear in mind that without documented obtained informed, dated, and signed consent (where this is a requirement), a person cannot be included in the study and the person’s data cannot be used. Data from non-participating individuals can in general not be used for dropout analysis. Dispensation from access to confidential information in research projects Applications for dispensation are necessary for research based on confidential health and personal data information obtained by the healthcare service without consent from each individual patient. When applying for dispensation to allow access to confidential information in quality research studies and other research studies that use health data, the legislation is complicated. It is recommended to clarify such 55 questions with the Data Protection Officer at your institution before a dispensation application is submitted. If the researcher is to have access only to anonymous data, it is not necessary to apply for a dispensation. This presupposes, however, that those who disclose the health data have legal access to the relevant information. An example of this is where healthcare officers and others with legitimate access to the data retrieve information from a medical chart or other health registries and then anonymize and disclose the data to the researcher. For internal quality assurance studies of health services within a health trust/hospital, there is no requirement for approval from any external authority (The Health Personnel Act § 26). Internal quality registries are subject to notification to the local Data Protection Officer or the Norwegian Data Protection Agency. The Research Director (“forskningsansvarlig”), the Data Processing Director (“databehandlingsansvarlig”), the Project Manager (“prosjektleder”), and other personnel involved in a research project have a duty to provide information to the supervisory authorities. The Norwegian Board of Health Supervision should be notified in writing in cases of “serious, unwanted and unexpected medical events that are believed to be related to the research. The Data Protection Agency can rule that any processing of health information opposing the provisions of the Health Research Act must cease. Alternatively, the Data Inspectorate can stipulate conditions to be fulfilled before the processing of health information may be initiated/continued in a research project. In the final report, results are to be presented in "an objective and reliable manner". Final reports should have a limited, abstract like format; in line with final reports for interventional trials in the “clinical trials system” (see Chapter 9). It is important to note that a too detailed presentation of results before a study has been submitted for publication may be considered an attempt at duplicate publication by certain journals, and they may therefore not wish to publish the article. There are strict requirements for the implementation of drug trials regardless of whether it is an early testing phase or the drugs have previously been approved and used for many years in clinical therapy. The definition of a clinical drug trial is “any systematic study of a drug made for humans with the aim of gaining or verifying knowledge about 58 effects on physiological function, interactions, side effects, uptake, distribution, metabolism, or excretion of the medicine concerned, or the study of its therapeutic value”. The regulations also apply to marketed preparations (regardless of how long they have been in use) and include health economics studies. The regulations do not cover experimental treatment of individual patients or non-interventional studies. Gene therapy studies must also be reported to the Health Directorate (see Chapter 6. Normally, each center will have a responsible project collaborator who will be under the command of the national coordinator (Project Manager) (§ 6 of the Regulation on the organization of medical and health research, see Appendix). In such cases it is important that the disclosure of personal health data from each center is carried out in accordance with the Personal Data Act on Information and that such disclosure is based on an agreement between the collaborating institutions. Also, in these cases it is important to obtain the necessary advice and assistance from the Data Protection Officer or equivalent support functions.
