Nicotine causes narrowing of blood vessels generic 100mg lamictal with mastercard, which then affects the circulation and causes blood pressure to rise order lamictal 25 mg without a prescription. This is why regular absorption of nicotine through smoking can cause chronic heart problems and increases the possibility of heart attacks lamictal 25mg online. Tar released in the form of particles in the smoke is the main cause of lung and throat cancer in smokers and also aggravates bronchial and respiratory disease. Smoking is known to increase the incidence of a wide range of medical problems including:- lung cancer heart attacks angina emphysema chronic bronchitis asthma cancer of the cervix depression strokes high blood pressure bladder cancer throat cancer tongue cancer oesophageal cancer kidney cancer pancreatic cancer small and sicker babies of pregnant women sinusitis viral and bacterial infections of the throat and lungs (eg. Many of the effects above may affect not only the smoker, but also those who live and work with smokers (passive smokers). It contributes to more deaths than alcohol and illicit drugs together, and costs the economies of these countries millions of dollars a year. There is no doubt that the babies of mothers who smoke are smaller (by 200 g on average) than those of non- smoking mothers. The smoking by the mother appears to reduce their resistance to disease, in particular to infection, so that babies born to smoking mothers die in infancy more often than average. By inhaling the smoke from either of their parents, these infants have more colds, bronchitis and other respiratory problems than babies in non-smoking homes. Any woman who smokes should ideally cease before she falls pregnant, but certainly should do so when the pregnancy is diagnosed. This is far easier said than done, but if her partner stops at the same time, support and encouragement is given by family and friends, and assistance is obtained from the family doctor, women who are motivated to give their baby the best possible chance in life will succeed in kicking this very addictive habit. The patient remains awake, but is often sedated, while an anaesthetist or surgeon places a needle into the lower back. The needle is inserted between the vertebrae so that the tip enters the spinal canal, which contains cerebrospinal fluid and surrounds the spinal cord. The spinal cord carries all the nerve messages to and from the brain, and runs through the centre of the 24 vertebrae that form the backbone. A small amount of anaesthetic is injected into the spinal canal, so that the nerves below the level of injection no longer work and pain from the operation cannot be felt. The patient is often tilted slightly to prevent the anaesthetic from flowing further up the spine and affecting nerves above the level required for adequate anaesthesia. The side effects of a spinal anaesthetic include low blood pressure, a headache for several days, and a slow heart rate. This type of anaesthetic is usually given when the patient is not well enough to stand a general anaesthetic, for Caesarean sections, and in other circumstances when it is desirable for the patient to be awake. They are caused by a break down and stretching of the elastic fibres in the skin by changes in the body’s hormone levels as well as direct stretching of the skin. Once they form they usually remain permanently unless removed by plastic surgery or reduced by creams containing retinoic acids. Cushing syndrome is caused by an over production of steroids such as cortisone in the body, or taking large doses of cortisone. Headache, obesity, thirst, easy bruising, impotence, menstrual period irregularities, stretch marks, acne, high blood pressure, bone pain and muscle weakness are common symptoms of this syndrome. In many patients, the symptoms are so mild that they are ignored, but in severe cases the patient complains of a low-grade fever, tiredness, muscle aches, joint pains, headache, sore throat, a mild rash and enlarged glands. The disease can be detected by a specific immunoglobulin blood test, and this test is often routinely performed during antenatal blood examinations. Unfortunately, because the disease has already occurred, there may still be some damage to the foetus. During the first trimester (the first three months) the structure and form of the foetus are developed. The second trimester is involved with the growth of the foetus while the third trimester is the maturity of the foetus. This allows a woman to attempt a natural vaginal delivery while a medical team is readily available to intervene with forceps or surgery if necessary for the health of the mother or baby. It is located in the pelvis and is loosely tethered to the pelvic walls by two ligaments on each side, the round and broad ligaments, giving it a high degree of mobility. The upper part of the uterus is called the body, and is attached to the two egg-conducting Fallopian tubes. It narrows at the lower end to form the cervix, or neck, which protrudes into the vagina and provides a passage for sperm to enter and menstrual blood to flow out. In the middle is a thick layer of muscle called the myometrium, while the inner lining consists of a blood enriched mucous membrane called the endometrium. If this does not eventuate, all but the deepest part of the endometrium is discarded, leading to the monthly menstrual period. The menstrual flow consists of the liquefied dead endometrium together with some blood lost in the process. They expand to accommodate the growing foetus, and when the time comes for the baby to be born they engage in a series of contractions, helping the hitherto tightly closed cervix to open and propelling the baby into the vagina during labour.

Anaesthetists are in the unique position that they can offer all of these skills lamictal 25mg without a prescription, and the ultimate responsibility for pre-operative anaesthetic assessment lies with the anaesthetist discount lamictal 200 mg free shipping. Preparation for surgery may take weeks to achieve discount lamictal 100mg amex, and could therefore potentially cause delay and cancellation of surgery if not done adequately. Pre-operative anaesthetic assessment services decrease cancellations on the day of surgery, improve the patient’s experience of their hospital admission, and may reduce complication rates and mortality. The pre-operative visit may relieve anxiety and answer questions about both the anaesthetic and surgical processes. Complications and malpractice lawsuits are often attributable to poor preparation and failures in communication. Specialist anaesthetic pre-operative assessment nurses have been shown to be safe and effective at pre-operative screening and should be an integral part of the team. Before planned admission Pre-operative services should: • Ensure every patient* is fully informed about their proposed procedure and the interventions that will need to be undertaken. The visit to the pre-operative clinic also gives the patients an opportunity to discuss the choices of anaesthetic technique, methods for pain relief and the risks, in a calmer atmosphere than immediately before the operation. Senior anaesthetists with a special interest in pre-operative assessment are ideally suited to this role. There are several models available for the pre-operative anaesthetic assessment clinic, most of which rely both on anaesthetists and specialist nurses. A well-designed peri-operative service will decrease the instances of failure to proceed to surgery due to communication or administration errors. Electronic systems can greatly help with decision-making, communication and analysis, and can prevent errors. Pre-operative primary care Primary care can help optimise patients’ fitness before surgery by offering advice on smoking cessation, exercise and weight reduction, and by optimising treatment of chronic conditions such as diabetes and anaemia (female <12 g. This may help increase survival, decrease peri-operative-1 morbidity and shorten the duration of hospital admission. This could take the form of accessing smoking cessation clinics, dietary advice and exercise regimens. Early referral by primary care and surgical teams for pre-operative management will increase efficiency. Nurse-led pre-operative assessment Pre-operative anaesthetic assessment is an extended role for nurses that has been shown to be safe and cost effective [3- 5]. These nurses usually work as an integral part of the pre- operative team and are a very important link between the patient and the entire peri-operative team. Nurses should work closely with the anaesthetists involved in the service and have good communication skills and links with the rest of the hospital. Their purpose is to contribute to the pre-operative preparation of all patients, to identify patients with a high peri-operative risk, to institute investigations and to refer to the anaesthetist, as well as to assess patients for suitability for day surgery. In addition, they will implement the various pre-operative protocols, including fasting and administration of regular medication, and are able to answer many of the patient’s questions about their anaesthetic. Protocols should empower the nurses to refer patients to relevant services such as echocardiography when there is a 9 history of a heart murmur, or pulmonary function tests for chest disease. These protocols should be written by senior anaesthetic staff and should be regularly reviewed and updated. In-clinic spirometry is useful and easy to perform, and may decrease the number of patients referred for formal pulmonary function tests. Pre-operative assessment nurses should co-operate closely with primary care services, particularly when administration of specific medication is required, such as subcutaneous anticoagulation or optimisation of diabetic treatment. Liaison with secondary care diabetes teams and medical outreach teams can be particularly helpful and may prevent unnecessarily long stays in hospitals, both pre- and post- operatively. It is important that pre-operative assessment nurses have readily available communication channels with pre-operative assessment anaesthetists; they should be able to discuss specific cases and receive feedback from the anaesthetist. The anaesthetist in the pre-operative assessment clinic Senior anaesthetists with a specialist interest in pre-operative assessment and optimisation should staff pre-operative assessment clinics with the number of sessions needed being dependent on the throughput of the hospital and its casemix. These anaesthetists should see all patients who are potentially at high risk, make an assessment of the risks and benefits of surgery and ensure that patients: • Are confident that they want surgery. The pre-operative assessment anaesthetist therefore needs to be skilled at assessing and managing these risks, and in communicating them both to the patient and to the treating surgeon. Consultant-to-consultant communication between anaesthetists, surgeons and critical care physicians is essential, particularly when the patient is high-risk and the benefits of surgery may be outweighed by the risks to the patient. Multidisciplinary meetings should help anaesthetic consultants identify and manage high-risk cases, particularly when major surgery is planned. Risk prediction can be used to guide the patient’s pre-operative care and determine whether the patient needs to see an anaesthetist in the pre-operative assessment clinic. These thresholds can be used as markers to help hospitals determine the level of resources they need to invest to provide their catchment patient population with adequate pre-operative services. Diagnosed peripheral arterial disease Pre-operative and post-operative risks of mortality and morbidity can be estimated with these variables when adjusted for surgical disease and surgical procedures respectively (see Appendix 2). Resources and funding Setting up pre-operative services where none exist requires a substantial time commitment in order to put in place the infrastructure, to recruit staff and to oversee the organisation, administration and processes at all levels.

In addition to the increase in ocular size also comes a much larger and stronger orbicularis oculi muscle. Questions not only relating to the chief complaint and recent history, but also to previous ocular problems with this animal and relatives as well as any current or past problems with animals stabled in the same environment. The Ophthalmic Examination Examination Environment  The examination environment is important and can greatly influence the examination results. In an environment that is too distractive and bright, a complete careful examination can not be done; especially in an animal that is unruly. Introductory Examination Process  Initially a cursory physical examination and gross examination of the head and ocular region prior to any sedation or local anesthesia is advisable. First and foremost one should determine if the animal is sighted  The menace response is acceptable, but even prior to that, note how the animal is reacting to its surroundings. For example, how the animal behaves while being unloaded from a trailer, or while turned out in the paddock. Watch carefully as the animal is being led on a lead and how it reacts to other animals and its environment. First and foremost one should determine if the animal is sighted  An obstacle course would be ideal yet in my experience it is not always practical. First and foremost one should determine if the animal is sighted  The history with these animals will commonly include frequent trauma and difficulty navigating at night or in dim light. Vision Testing The menace response is a learned response which will not generally be present in foals less than two weeks of age. A hand or finger(s) thrust is made toward the eye, avoiding setting up stimulating air currents, or touching tactile hairs (vibrissae). Therefore, the seventh cranial nerve and orbicularis oculi muscle must also be intact along with visual pathways up to and including the cortex. When performing this test the examiner should stand on one side of the animal to assure that his hand motion is not in the visual field of the contralateral eye. The strength of the blink response can be amplified by actually touching the periocular region on the first one or two thrusts and then stopping short of this on the next two or three. Some animals need to be reminded, if you will, that the thrusted finger may touch them. Vision Testing  Throwing cotton balls, wads of cotton or a glove in the air can be helpful in visual assessment but it is not always reliable. Vision Testing  The end point with this method would be head motion and /or reflex blink, which can be subtle. The examiner needs to be assured that the object thrown is large enough to be seen, that the object does not make a noise, set up stimulating air currents, nor is thrown into the visual field of the opposite eye. A few repeated responses are necessary to avoid interpreting a coincidental blink or head motion with a positive sign. Vision Testing  Throwing Cotton Balls Gross Evaluation  Symmetry  Ocular discharge  Normal Position of the Upper Eyelid Cilia  Ptosis  Blepharospasm  Photophobia  Surface Topography  Pupillary symmetry Symmetry  Evaluate symmetry of the head and facial expression. Ocular discharge  Ocular discharge if present should be characterized as serous, mucoid, purulent, hemorrhagic, seromucoid, mucopurulent, or serosanguinous. Normal Position of the Upper Eyelid Cilia  The position of the upper eyelid cilia normally should be directed nearly perpendicular to the corneal surface. Blepharospasms  Blepharospasm (forced blinking) is usually a sign of ocular pain and commonly is also associated with an ocular discharge. Photophobia Ocular pain that results in blepharospasm can stem from superficial sites (eg: cornea) or deep intraocular ones (eg: uvea-ciliary spasm).

You may also be required to complete one or two topic presentations—in some past years generic 100mg lamictal with amex, all students have been required to complete one presentation on psychiatric aspects of a chronic disease generic lamictal 25 mg line. Be extra careful about dressing professionally on psychiatry buy generic lamictal 100mg online; remember that cleavage or flashy clothes might give the wrong signal to a confused patient. Some helpful hints for psych: • This is the only rotation where you don’t shake your patient’s hand when you walk in the room. This means never putting the patient between you and the door, never doing anything you feel uncomfortable with, and adhering to any guidelines that your residents and attendings create. Mental Status Exam: The psych H&P is similar to the general H&P, but it is important to pay extra attention to the past psych history, family psych history, drug and alcohol history, and social history. Behavior: Include gestures, abnormal or idiosyncratic movements (akathisia, automatisms, catatonia, choreoathetoid movements, compulsions, dystonias, tardive dyskinesia, tics, tremors, etc. Cooperation/reliability: Pay attention to patients’ cooperation/attentiveness to the interview and their attitude/demeanor. Speech: Note rate, quantity, quality (volume, rhythm), and form, as well as any difficulty speaking (i. Thought Process: This is the form or structure of the patient’s thinking as opposed to the actual content. Impaired thought processes include looseness of associations, flight of ideas, word salad, thought blocking (sudden interruption of thought and speech), racing, etc. Includes delusions, suicidal/homicidal ideation, paranoia, somatic or religious pre-occupation, other obsessions, grandiosity, helplessness, ideas of reference, ideas of thought control or thought broadcasting, thought insertion, beliefs of unusual powers, phobias, fears, feelings of worthlessness or guilt, and feelings of being punished. This is the internal emotional state that you believe to be present—may not match the patient’s affect. The sites also vary in terms of hours and expectations, so try to find out from your friends about the various sites. Throughout the rotation, you will meet regularly for lectures that will cover a lot of the material you will need for the shelf. The inpatient experiences should be very similar to your core rotation in inpatient medicine in that you will help admit, work up, manage, and follow specific patients throughout the course of their admission. On a consult service, you will see how neurologic issues may affect patients on other specialty services. Presentations and notes should follow the standard format, with the addition of a directed neurologic history, comprehensive neurologic exam, and underlying appreciation for relevant neuroanatomy. You may be asked to prepare a topic presentation to present to your team—see the “Sample Documents” packet for an example of a Neurology topic presentation. With pediatric patients, keep in mind that at different ages, some aspects of the neuro exam are not applicable or need to be approached in a different manner. You may want to get a copy of the Denver developmental 51 milestones sheet to get an idea of what is appropriate behavior given a child’s age. Neurologic Exam Cranial Nerves: I: Olfactory: most do not try to test this; if you are really on top of your game, you may have a vial of something with an odor. As a student, you can stuff your white coat with a light pen, toothpicks or wooden cotton swabs, reflex hammer (or use the end of your stethoscope), tuning forks (if you really have it together), and an ophthalmoscope (if you have one or have friends from whom you can borrow one— definitely not necessary though). Ophthalmology The Ophthalmology week begins with an introductory session on the eye exam, use of the slit lamp, and looking at each other’s fundi. Be prepared to have your eye dilated and remember your ophthalmoscope, if you have one or can borrow one (but don’t worry if you don’t have one—you can share with other students). Be sure to look at these photographs as a good portion of the exam at the end of the week consists of slides from the book. You will have the opportunity to practice a complete head and neck exam on each other and see a laryngoscopy. They have recently been cracking down on attendance, so try to assess what is expected of you in the beginning of the week. You will be given a set of questions and answers covering basic orthopedic topics and the exam questions at the end of the week will be drawn directly from these questions. Surgery/ Emergency Medicine/Anesthesiology The combination of these three disciplines into a single clinical block allows for an integrated curriculum to best present clinical issues commonly encountered among practitioners in all three fields. Lectures and case- and problem-based learning sessions will address interdisciplinary topics including shock, fluids and electrolytes, hemodynamics, coagulation, peri-operative management, and trauma/critical care. Additionally, rotation-specific curricula will address topics more relevant to each discipline to compliment your clinical experience.
